Role of the liver in the disposition of intravenous nitroglycerin in the rat

Previous studies have indicated that the liver is the main site of nitroglycerin (NTG) elimination when the drug is systematically infused. To examine this hypothesis, we measured the apparent systemic clearance (Cls) of nitroglycerin in anesthesized rats receiving a constant intravenous infusion at a dose of 100 micrograms per kg per min. Animals were divided into shunt and sham groups; the former had undergone a portal vein ligation 10 days prior to the study, while the latter was subjected to a sham operation. On the study day, half of the animals of each group also received probenecid at 200 mg/kg, i.v., a drug previously reported to inhibit organic nitrate ester reductase (ONER) activity in rat liver. Arterial NTG samples were obtained at 41, 43 and 45 min of infusion in all four experimental groups; Cls was 439 +/- 32 ml per kg per min (mean +/- S.E.) in sham, 460 +/- 44 in sham and probenecid, 477 +/- 39 in shunt, and 461 +/- 34 in shunt and probenecid animals. During NTG infusion, hepatic blood flow (measured with a constant infusion of indocyanine green) was decreased markedly in shunted rats as was liver/body weight, indicating hepatic atrophy. The specific activity of hepatic ONER was similar in all four groups. In spite of marked differences in hepatic blood flow and hepatic mass, the Cls was similar in all four groups. The liver does not appear to be a major site for the elimination of systemic nitroglycerin as hitherto assumed.

Nifedipine in the treatment of hypertension in the elderly

The effect of nifedipine monotherapy, retard tablets, 20 mg bid, was evaluated in 23 hypertensive patients, mean age, 79 +/- 2 years. Twenty-one patients completed an eight-week study. Blood pressure (BP) decreased to 160/90 mm Hg in 15 patients; in four additional patients diastolic BP dropped by 15% to 28%. In a subset of five patients with isolated systolic hypertension, a significant reduction in systolic BP was noted. Side effects were relatively mild and only two patients discontinued the study. The results suggest that nifedipine monotherapy offers an alternative, logic, therapeutic approach to hypertension in the elderly.

The role of the gut flora in the reduction of sulphinpyrazone in the rat

Sulphinpyrazone underwent both reduction to a sulphide and oxidation to a sulphone after parenteral administration to normal Wistar rats. Oral administration was associated with a bioavailability of about 75% and with a 3-fold greater formation of the sulphide. However, no sulphide was detected in the plasma after oral administration of sulphinpyrazone to germ-free (BD/X) rats or normal rats treated with oral antibiotics. In vitro studies showed that the major site of reduction of sulphinpyrazone was the contents of the hind gut with little activity detected in the liver or other tissues. The sulphide was oxidised in vivo to sulphinpyrazone and small amounts of sulphone, while the latter underwent only slight reduction to sulphinpyrazone, but did not give detectable levels of the sulphide. These data suggest that the gut microflora are the main site of reduction of sulphinpyrazone in the rat in vivo.     

Pharmacological analysis of the participation of the catecholaminergic system in the development of the abstinence syndrome in rats

The behavioural activity of rats in "the open field" was studied. It was revealed that rats alcoholized for 8 months do not practically differ in their behavioural indicators from the intact ones. After the discontinuation of alcohol marked disturbances appear in their behaviour, that are arrested by apomorphine (0,1 mg/kg). In intact animals dopamine (50 mkg into the brain ventricles) induces behavioural disorders similar to those in rats during abstinence. Noradrenaline does not induce similar disorders. A conclusion is made on the dopaminergic nature of disorders in the behaviour of rats in the state of alcohol abstinence.     

Problems in the evaluation of hypnosis in the treatment of alcoholism

Although hypnotherapy has been applied to alcoholism for over a century and is accepted by the AMA as a medically valid technique, the effectiveness of hypnosis in treating alcoholics remains controversial. Systematic evaluation has been hampered by the unique role of hypnosis as a cultural artifact, by problems in defining and verifying hypnotic intervention, by individual and situational variation in hypnotizability, and by difficulty in separating hypnosis from the therapies to which it is applied. Clinicians using hypnosis are likely to continue to base their claims for its effectiveness on intuition, especially since no study has demonstrated that hypnotherapy is contraindicated for patients requesting its use.
