Dantrolene dantrium ; is an alternative to baclofen and tizanidine if both drugs are ineffective or not tolerable. P-0.02 ; was only reduced to a degree similar to that seen in the groups treated with either drug alone: FK506 820 mluminug KW, P-0.02 ; or SRL 819 mluminug KW, P-0.02 ; . In the three groups where only a single drug was used, the reduction in GFR agreed with earlier findings for the calcineurin inhibitors [10, 11]. Whole blood concentrations of the immunosuppressive agents, CsA and FK506 Whole blood trough concentrations of CsA did not differ significantly between the group receiving CsA alone 843"343 nmolul ; , the group receiving CsA plus SRL 700"329 nmolul ; , and the group receiving CsA plus FK506 722"275 nmolul ; the KruskalWallis ANOVA was 0.966; Ps0.62 ; . Nor did the whole blood concentrations of FK506 vary significantly between the groups: the group receiving FK506 alone 1.3"1.0 nguml ; , the group receiving FK506 plus SRL 1.5"1.4 nguml ; , and the group receiving CsA plus FK506 2.0"0.7 nguml ; the KruskalWallis ANOVA was 3.70; Ps0.16 ; . Effect on blood pressure The results of the blood pressure measurements are given in Figure 2. Neither the intra-arterial systolic blood pressure nor the diastolic blood pressure displayed significant changes, as the KruskalWallis ANOVA was 9.71 Ps0.13 ; for the systolic blood pressure and 12.05 Ps0.07 ; for the diastolic blood pressure. Effect on renal morphology A total of 83 kidney biopsies were examined. The biopsies were stratified according to the treatment.

Dantrolene and calcium In accord with other studies on muscles exposed to high frequency stimulation 13, 31 ; , Mwave area and amplitude were, in the present study, well maintained during the first seconds of 60Hz stimulation Figure 6 ; but then declined at a fast rate as stimulation was prolonged. A similar two-phased development was observed in the force production of control muscles Figure 2 ; , and Figure 7 shows that in these muscles force was significantly correlated to both M-wave area r2 0.61, P 0.001 ; and M-wave amplitude r2 0.89, P 0.001 ; during the 30s of 60Hz continuous stimulation.

Palmitic acid 2.40 KIM ; stimulated basal as well as insulin-stimulated glucose incorporation in rat adipocytes three- and twofold, respectively. Similar degrees of stimulation of basal glucose oxidation by palmitate were also observed. The ability of palmitic acid to stimulate glucose uptake was additive with respect to the stimulation induced by insulin and was proportional to the palmitic acid concentration between 0.15 m and M 2.40 mM. Stimulation of glucose incorporation by palmitic acid was inhibited by preincubating the cells with quin2-AM, which accumulates intracellularly yielding the trapped chelator form, quin2, which binds intracellular CaZ + .The concentration of quin2-AM required for half-maximal inhibition of palmitic acid 1.2 ~ L M mean f stimulated glucose incorporation was 3.8 SEM ; . The inhibition of palmitic acid-stimulated glucose incorporation by quin2-AM 10 ; was overcome by incubating cells with the CaZrionophore, A23187, in the presence of extracellular Ca2 + 2.6 m M ; . Chelation of extracellular Ca2' with EGTA did not significantly affect the magnitude of palmitic acid-stimulated glucose incorporation. Dantrolene 12.5-100 ~ L M ; failed to affect basal or palmitic acid-stimulated glucose incorporation. These findings suggest that palmitic acid stimulates incorporation of glucose in the adipocyte by a mechanism dependent upon intracellular but not extracellular Ca2 + . Thode, J., H. A.

The time of start of treatment extends from two days to four hours before anaesthesia. Kerr84 found that a single oral dose of 8 mg-kg"1 four hours before halothane challenge is as effective as smaller but multiple doses of dantrolene. Gronert59 has shown that pretreatment with 5 mg-kg"1 intravenously prevents, 1-3 mg-kg"1 attenuates and 0.1 mg-kg"1 has no effect on induction of reactions in MHS swine by halothane and succinylcholine. Flewellen and Nelson 8586 reported that the intravenous dose of dantrolene which produced 95 per cent of maximal muscle relaxation i.e. reduction of toe twitch tension ; is sufficient to prevent effectively MH crises in swine. They determined that this dose is 3.5 mg-kg"1. They also discovered that this same dose corrects already established MH reactions. Oral dantrolene has also been used extensively in preanaesthetic prophylaxis of MHS patients.45 87~92 However, the true value of dantrolene pretreatment in patients remains largely unknown since for ethical reasons no one has ever been given any potent inhalational anaesthetic or depolarizing skeletal muscle relaxant following a course of dantrolene. Rather patients have been anaesthetized with drugs known to be safe for MHS patients. Therefore, even without dantrolene pretreatment, an MH reaction would have been unlikely. However, we are aware of one patient who was treated with only 3.0 mg-kg"1 per day for two preoperative days and developed a MH reaction during anaesthesia with droperidol, fentanyl and thiopentone, pancuronium and cocaine. 90 ' 93 the other hand, no human pretreated with at least 4.0 mg-kg"1 of dantrolene has been known to have developed evidence of MH during anaesthesia. At present the choice between use of prophylactic dantrolene or reliance only on administration of "safe" anaesthetics is a difficult one. 94 Unfortunately, the effective prophylactic dose of dantrolene is similar to that at which adverse side effects occur.94 9S In a recent study, Flewellen etal.96 have found that neostigmine does not reverse dantroleneinduced depression of muscle function. They warn that this might contribute to respiratory inadequacy in the postoperative period.94 In our hospital prophylactic dantrolene is given to known or suspected MHS patients only in the following situations and darifenacin.

The parameters are defined in the text. Desflurane anesthesia. The increase in end-tidal CO, was sudden from 29 to 85 over 10 mm ; , not gradual over 90 mm, as cited by Mayhew and Lowes. Also, the occurrence of vigorous inspiratory efforts paralleled the increase in end-tidal CO, . Had the forced respiratory efforts been caused by diminishing neuromuscular blockade, as suggested, we would have expected them to occur earlier. Neuromuscular blockade after an intubating dose of vecuronium lasts approximately 40 mm in peripheral muscles. Respiratory muscles, especially the diaphragm, have a significantly faster recovery from neuromuscular blockade 2 ; . Furthermore, end-tidal CO, continued to increase, despite hyperventilating the patient by manual assistance twofold increase in minute ventilation up to lo-12 L mm ; . Another symptom of MH, an increase in core temperature, did not occur gradually, as might be expected if it were caused by excessive draping, but started parallel with the increase in CO, the temperature remained stable at 36.5 ? 0.2"C for 60 min, followed by an increase to 37.8"C in the next 35 min ; . In the case reported, a short procedure was anticipated, which was only prolonged because of a technical fault. Therefore, the patient was not particularly draped and protected to prevent heat loss. Contrary to the statement of Mayhew and Lowes, it is, in our experience, rather difficult to avoid unwanted cooling of patients in the setting of cerebral angiography. Therefore, there is no doubt that the increase in temperature observed in this patient was unusual. We agree with Mayhew and Lowes that the increase in heart rate was not dramatic in our patient. Nonetheless, an increase in heart rate in the absence of surgical stimulation is another criterion for the diagnosis of MH, also included in the clinical grading scale of MH. Thus, the combination of hypercarbia, temperature increase, and tachycardia yields 33 points on the clinical grading scale 3 ; , which accounts for our scoring the likelihood that the observed event was MH as "somewhat greater than likely." Mayhew and Lowes also criticize our management. As mentioned in our report, the boy's trachea was extubated because he fulfilled standard extubation criteria; he was responsive and demonstrated adequate muscle strength. The angiography room in our neurosurgical department is a remote area to provide anesthesia. Because the boy was stable, we believed that it was safe to transfer him to the intensive care unit for further treatment, instead of waiting for the dantrolene to arrive, which would have taken as long as the transfer. A starting dose of dantrolene therapy, according to textbooks, is 2-3 mg kg. In that respect, the dose of dantrolene administered to our patient was small. The dose, however, was based on the clinical course of the episode and the patient's stable condition. Because the patient did not show any further signs of increased metabolism, we believed that it was safe to discontinue the dantrolene infusion. We do not believe that the consequences of not being tested immediately for MH are as serious as is feared by Mayhew and Lowes. The patient and his parents have been informed about the nature and the implications of MH. The boy has been issued a MH warning card and will, for the time being, be considered as if he were confirmed to be MH-susceptible. He will be treated accordingly until a muscle biopsy is performed. Because of the genetic nature of MH, we decided to test the mother first, according to the dictum mater semper cerfa est. The patient's father is also scheduled for muscle biopsy, although a negative result will be of no consequence to the boy. In conclusion, had we not suspected MH in this patient, the boy's family, now proven by in vitro contracture test to be MHsusceptible, would have remained undiagnosed.

Correlation between ED and ischemic heart disease ED is a wide spread and troublesome condition among middle-aged men and is partly vascular in origin. The Massachusetts Male Aging study investigated the relationship between baseline risk factors for coronary heart disease and subsequent ED, on the premise that subclinical arterial insufficiency might be manifested as ED. The authors concluded that ED and coronary heart disease share some behaviorally modifiable determinant in men Feldman et al. ; . Risk factors for ED include many of the same risk factors for cardiovascular disease: lipid abnormalities, including decreased HDL, cholesterol, smoking and diabetes Virag et al.

The adequacy of 'total' autonomic block in the present study is important in interpreting the differences in magnitude of non-autonomic effects on TPRI between hypertensives and nornnotensives. Although the dose of each autonomic blocking drug used in the present study is as great as any previously used in man, it is smaller than the dose necessary to block the appropriate effectors during maximal physiological stimuli in animal experiments.l9' 24, 25 The results with cardiac block are substantially in agreement with previous findings of Jose and Taylor, '8 and of Julius, Pascual and London.'0 After 'total' autonomic block the rapid reduction inr mean arterial pressure during the period of raised intrathoracic pressure in the and desipramine.
