D. Jacobson-Kram. Center for Drug Evaluation, US Food and Drug Administration, Rockville, MD. Paracelsus over 400 years ago pointed out that "All substances are poisons.The right dose differentiates a poison and a remedy." Thresholds for toxicities are a basic tenet of toxicology. With the exception of carcinogenicity and mutagenicity, all chemically-induced adverse health effects are thought to have thresholds, exposures below which there is no increased risk for the adverse effect. In drug development, "margins of safety" the difference between the therapeutic and toxic doses ; are used to define risks associated with particular drug therapies. ICH guidelines Q3A and Q3B have defined thresholds for reporting, identification and qualification of impurities in drug substances and drug products, respectively. ICH Q3C describes risk assessment methods for residual solvents. Implicit in these guidelines is the notion that exposures to impurities and degredants below a certain level convey no significant risk of adverse effect. Mutations and cancers associated with genotoxic chemicals are generally viewed as lacking a threshold, i.e., every exposure conveys some additional risk. Because it is also generally agreed that complete elimination of such exposures is not possible, regulatory agencies have adopted risk assessment strategies designed to define acceptable exposure levels to such agents including genotoxic impurities in drugs. Such exposures are referred to as "thresholds of toxicological concern" TTCs ; and specify lifetime daily exposures which result in increased risks of no more than 1 in 100, 000 or 1 in 1, 000, 000.

After the APhA Annual Meeting in March, our chapter held its 2006-2007 board elections. We welcome the new 39 board members and look forward to a successful year. The new board is already working on community programs and health fairs for the summer. We are also looking forward to our annual summer leadership retreat, where we will learn our team dynamics and begin to prepare for the upcoming school year. In April, several USC students attended the first annual CPhA Student and New Practitioner Summit. The students enjoyed the educational and fun weekend, and we are looking forward to next year's summit! We'd also like to thank our representatives on the steering committee, Sheena Patel and Estella Wu, for doing a great job to help organize the summit. Also in April, USC student pharmacists participated in recruitment for the Diabetes Ten City Challenge- a nationwide effort sponsored by APhA, and the APhA Foundation to establish the value of ongoing pharmacist-provided patient care. At two spring health fairs, coordinated by Dr. Edith Mirzaian, Pharm.D., student pharmacists educated and screened USC Employees for diabetes while recruiting participants for the Challenge. In continuing to build our relationships with legislators, our student pharmacists have been involved in several Medicare Part D workshops hosted in April by California Assembly Speaker, Fabian Nunez. Students were trained to use the Medicare website to help patients choose a plan based on their medications. We then visited various community centers in the Los Angeles area and educated patients about Medicare Part D while saving them money on their prescription drug plans. In addition, several students, including our incoming Director of Legislative Affairs, Kristin Khalaf, have attended legislative fundraisers hosted by the United Pharmacists Network Inc. Most recently, students have had the chance to meet such legislators as California Senator Jackie Speier, as well as a California State Assembly candidate Anthony Portantino. As student pharmacists, we hope to continue building upon these relationships as the importance of grassroots efforts for the profession of pharmacy continue to grow. For this summer, USC student pharmacists will be participating in a number of health fairs and community service programs. In May, we worked in conjunction with the USC NCPA Chapter and took part in the Healthy Lifestyles for the 21st Century Expo hosted by L.A. Care. The event was held in Long Beach and students helped educate patients on healthy nutrition and lifestyle behaviors. On June 3rd in the East Los Angeles community, we held our first interdisciplinary health fair, along with the USC Schools of Medicine, Physical.

Voluntary preferred drug list mandatory will reduce prescription drug spending by an estimated .1 - .1 million general revenue savings, .1 - .7 million ; while expanding the current list to include all major therapeutic categories will reduce spending by an estimated .5 - 8.8 million general revenue savings, .9 .4 million ; . In addition, supplemental manufacturer rebates for preferred drugs could result in additional rebates of up to 6% annual pharmacy expenditures, an estimated 2.3 million general revenue savings, .0 million ; . Developing and implementing a mandatory preferred drug list will require the agency to meet federal Medicaid law which requires a committee of doctors, pharmacists, and other appropriate experts to develop the preferred drug list. Federal law also requires that non-preferred drugs be made available through prior approval. Appendix C summarizes the federal requirements for a state establishing a preferred drug list and a prior authorization program. Direct the agency to develop and implement strategies to encourage compliance with using drugs on the preferred drug list. Medicaid provider compliance with a preferred drug list is critical to reducing pharmacy costs. The agency can encourage high compliance by providing incentives such as exempting preferred drugs from the four brand name prescription limit, giving higher dispensing fees for preferred drugs, and instituting patient co-payments for nonpreferred drugs and kaon.

Some groups have detected N-type CaV currents in HIT-15T, RINm5F, and INS-1 cells 89, 91, 96 ; . Contradictory to this, other groups reported that whole cell CaV currents in HIT-15T, RINm5F, and INS-1 cells were insensitive to -conotoxin GVIA 64, 89, 96 ; . The role of N-type CaV channels in insulin exocytosis is controversial. The N-type CaV channel blocker -conotoxin GVIA indeed gave a measurable inhibition of the second phase of glucose-induced insulin secretion from rat islets but had no effects on the first phase. The effect on the second phase of glucose-induced insulin secretion was attributed to toxic effects of the high concentration of -conotoxin GVIA used 53 ; . -Cell P Q-type CaV currents have been recorded in various types of -cells, including mouse, rat, and human islet -cells as well as INS-1 and RINm5F cell lines Table 2 ; . Recently, the presence of P Q-type CaV channels has been verified in the mouse islet -cell. A mixture of the L-type CaV blocker isradipine and R-type CaV blocker SNX-482 reduced CaV currents recorded from the mouse islet -cell by 80%. A cocktail of isradipine, SNX-482, and -agatoxin IVA almost fully blocked mouse -cell CaV currents 94 ; . The role of P Q-type CaV channels in stimulus-secretion coupling of mouse -cells remains to be examined. The involvement of P Q-type CaV channels in insulin secretion from rat -cells has been demonstrated by electrophysiological and pharmacological means 58 ; . The P Q-type CaV channel blocker -agatoxin IVA partially blocks HVA Ca2 currents in the rat -cell and inhibits the DHP-resistant component of glucose-induced insulin secretion by 30% 58 ; . Previous work showed that a portion of CaV currents and Ca2 -dependent insulin secretion in human islet cells remained in the presence of both the L-type CaV channel blocker nifedipine and the N-type CaV channel blocker -conotoxin GVIA 19 ; . Recently, 25% of human -cell CaV currents have been verified as P Q-type CaV currents by application of -agatoxin IVA. The effect of -agatoxin IVA on insulin release from human -cell is significant, but less than that of the L-type CaV channel blocker 96 ; . It was difficult to evaluate whether the R-type CaV channel was present in -cells and involved in Ca2 -dependent insulin secretion. These problems were solved by the application of mice lacking the CaV2.3 1E ; subunit and selective peptide antagonist of the R-type CaV channel 71, 76 ; . Pharmacological manipulation has dissected R-type CaV currents from whole cell CaV currents in mouse islet -cells and INS-1 cells Table 2 ; . The CaV2.3 subunit-selective peptide antagonist SNX-482 inhibits 60% of isradipine-resistant CaV currents in mouse islet -cells 94 ; . Evidence indicates that Ca2 influx through R-type CaV channels is coupled to insulin exocytosis 28, 76, 105, ; . CaV2.3-deficient mice exhibited disturbances in glucose tolerance and insulin secretion as well as hyperglycemia 76 ; . An appreciable proportion of the increase in mouse -cell capacitance, reflecting insulin exocytosis in response to depolarizations, can be blocked by SNX-482. Glucose- and KCl-induced insulin secretion from INS-1 cells was inhibited by SNX-482 in a dose-dependent manner 105 ; . Although the mouse -cell does not carry T-type CaV channels, they have been identified in human and rat islet -cells as well as in RINm5F and INS-1 cells Table 2 ; . Interestingly, the occurrence of T-type CaV channels has been observed in nonobese diabetic NOD ; mouse -cells 108 ; . The -cell T-type CaV channel is likely to be a player in and kenalog.

Infusions of serotonin 5 or 25 jig base min ; produced marked dose-dependent increases in perfusion pressure, small vein pressure, and cutaneous vascular resistance. Skeletal muscle vascular resistance was little affected by these infusion rates of serotonin. The increase in total vascular resistance in the cutaneous circuit was exclusively due to large artery and large vein constriction. The small vessels, if anything, tended to dilate. The differential action of serotonin on the skin and skeletal muscle vasculatures resulted in marked dose related shifts in blood flow from skin to skeletal muscle and keppra

Jensen, Kimmo, Morten Skovgaard Jensen, and John D. C. Lambert. Role of presynaptic L-type Ca2 channels in GABAergic synaptic transmission in cultured hippocampal neurons. J. Neurophysiol. 81: 12251230, 1999. Using dual whole cell patch-clamp recordings of monosynaptic GABAergic inhibitory postsynaptic currents IPSCs ; in cultured rat hippocampal neurons, we have previously demonstrated posttetanic potentiation PTP ; of IPSCs. Tetanic stimulation of the GABAergic neuron leads to accumulation of Ca2 in the presynaptic terminals. This enhances the probability of GABA-vesicle release for up to 1 min, which underlies PTP. In the present study, we have examined the effect of altering the probability of release on PTP of IPSCs. Baclofen 10 M ; , which depresses presynaptic Ca2 entry through N- and P Q-type voltage-dependent Ca2 channels VDCCs ; , caused a threefold greater enhancement of PTP than did reducing [Ca2 ]o to 1.2 mM, which causes a nonspecific reduction in Ca2 entry. This finding prompted us to investigate whether presynaptic L-type VDCCs contribute to the Ca2 accumulation in the boutons during spike activity. The L-type VDCC antagonist, nifedipine 10 M ; , had no effect on single IPSCs evoked at 0.2 Hz but reduced the PTP evoked by a train of 40 Hz for 2 s by 60%. Another L-type VDCC antagonist, isradipine 5 M ; , similarly inhibited PTP by 65%. Both L-type VDCC blockers also depressed IPSCs during the stimulation i.e., they increased tetanic depression ; . The L-type VDCC "agonist" ; BayK 8644 4 M ; had no effect on PTP evoked by a train of 40 Hz for 2 s, which probably saturated the PTP process, but enhanced PTP evoked by a train of 1 s 91%. In conclusion, the results indicate that L-type VDCCs do not participate in low-frequency synchronous transmitter release, but contribute to presynaptic Ca2 accumulation during high-frequency activity. This helps maintain vesicle release during tetanic stimulation and also enhances the probability of transmitter release during the posttetanic period, which is manifest as PTP. Involvement of L-type channels in these processes represents a novel presynaptic regulatory mechanism at fast CNS synapses and ketoprofen.

Quantitative imaging and electrophysiology in cortex high velocity stimulus Simons, 1978 ; . Finally, in this study the stimulator did not touch the whisker unless it was actively deflecting it. To obtain accurate data on the latency from the stimulus to the neuronal response, most studies of the whisker-to-barrel system position the whisker such that it touches the stimulator slightly even when it is not being actively deflected. In the present study the ability to measure latencies was sacrificed so as to avoid any habituation which might occur by chronically placing a stimulator against the exquisitely sensitive whisker. Using the present stimulation paradigm, significant evoked responses and detailed features of whisker evoked activity, such as afferent inhibition Carvell and Simons 1988; see Figure 4C, D ; , were clearly detected. An interesting feature revealed in this data set is the apparent drop off in cells with a significant evoked response at approximately one millimeter from the optical peak between distance 5 and 6; see Figure 8 ; . Up this distance, the great majority more than 80% ; of the cells recorded exhibited a significant evoked response to stimulation of the single whisker C2, whereas at distance 6 and beyond the percentage of cells is significantly lower. Perhaps this reflects a decrease in the efficacy of intracortical connections and information relay across the cortex. Anatomical evidence supports this, as tracers injected into a single barrel spread approximately 1.0 mm in all directions Hoeflinger et al. 1995 ; and individual supragranular neurons can spread even farther Gottlieb and Keller 1997 ; . A suggestive drop in the amplitude of both the intrinsic signal and the neuronal response amplitude are observed at a similar distance as the decrease in the percentage of significant cells, neither of these changes was significant. Unexpectedly, small but significant evoked activity was recorded in all cortical layers at.
