The single drug therapy of diazepam can be introduced to effectively control convulsions in eclampsia. This treatment will have particular application in rural obstetrics where eclampsia is seen in severe form. The dose schedule of diazepam, as described in this study, shows the therapy to have a stabilizing effect on hypertension and pulse rate. It causes neither respiratory depression nor oliguria. Diazepam is an effective muscle relaxant. Its depressive effect on the newborn is in no way inferior to that of lytic cocktail therapy. The drug is readily available at low cost, even in the remote rural areas, and can be easily administered by any doctor or midwife.

Lithium intoxication was induced in rats by intraperitoneal administration of lithium chloride in a daily dose of 200 mg/kg (0.22 LD50) for 6 days. Polyuria connected with pathological changes in the epithelium of the convoluted tubules and depression of the antidiuretic hormone--acid mucopolysaccharides system in the area of the straight kidney tubules was observed on the 6th day of the experiments. Oligouria and death of some of the animals on the 7th experimental day was caused by severe lesions the kidney structure. Further observation (30 days) demonstrated that, along with the regeneration processes, there developed a marked sclerosing ofthe kidney tissue. A conclusion was drawn that severe lithium intoxication was associated with the development of acute renal insufficiency. Functional reserves of the kidneys after the cessation of lithium chloride administration remained lowered for a long period.

A 62-year-old man spread maneb on about 200 sq m of garden and subsequently was taken to the emergency clinic with complaints of oliguria, diarrhea, and hoarseness. Based on the clinicobiochemical data, he was found to have acute renal failure; the serum levels of BUN, creatinine, and potassium were 144.3 mg/dL, 14 mg/dL, and 5.8 mEq/L, respectively. The ST segment depression in V4-6, reciprocal ST segment elevation in V1-3, and inverted T waves in V5 and V6 were recorded on ECGs. Both the renal failure and the ECG abnormalities disappeared after hemodialysis. The possibility exists that the maneb caused the acute renal failure.

A 38-year-old male developed acute oliguric renal failure following repeated glue sniffing for about 8 hours. In addition, he had severe liver cell injury, mild myonecrosis and bone marrow depression indicating generalized tissue toxicity. The high urinary spot sodium during the oliguric phase and the total renal functional recovery after a period of oliguria followed by polyuria favoured a diagnosis of acute toxic tubular necrosis causing acute renal failure. Toluene which is used as the solvent is presumably the toxic agent involved in glue sniffing. It is advised that toluene inhalation be considered in the differential diagnosis of acute renal failure especially in the young. Literature on the renal toxicity of toluene is briefly reviewed.

Renal metabolism of glucose and lactate was studied in ten adult beagle dogs during pentobarbital anesthesia. Six dogs were submitted to hypodynamic shock by means of an intravenous bolus injection of Escherichia coli endotoxin, 0.5 mg/kg over 15 min. Four dogs received only saline solution and served as controls. Sudden cardiac depression, hypotension and moderate renal hypoperfusion were observed in the endotoxin-injected animals. Acidosis and oliguria also occurred during the 5-hour study. Arterial and renal venous glucose concentration increased transiently during the early phase of endotoxin shock. In the control group glucose levels increased slightly by the end of the experiment. Despite marked hyperlactatemia in the endotoxin group, the arteriovenous lactate difference remained almost unchanged. Renal uptake of lactate and output of glucose were not influenced during the moderate renal hypoperfusion caused by endotoxin.

Lithium salts, in particular the carbonate and citrate, were formerly in widespread use, forming part of alkaline salt mixtures which were used for treatment of the many disorders belonging to the uric acid diathesis. Among these disorders were mania, depression, acute mania, acute melancholia and periodic depression. Satisfactory prophylactic effects on periodic depression were directly claimed. Daily doses of 3 to 26 mmol of lithium were recommended as standards. Only slight or moderate symptoms of poisoning were reported in a very few cases during the period in question (1860 to 1930), when the popularity of these lithium-containing prophylactic drugs with a favourable therapeutic index was at its peak. Lithium intoxication was not a serious clinical problem until 1949 when Cade introduced his fortuitously effective, but nevertheless high, dosage regimen which was continued until signs of recovery from mania appeared. For the maintenance dose, Cade in principle recommended, but seldom adhered to, 17 mmol/day. Chronic lithium intoxication starts insidiously with silent affliction of the kidneys followed by 'prodromal' symptoms, and when moderate severity has been reached, an accelerating renal vicious circle with decreasing kidney function is imminent. After this point the chronic intoxication resembles acute intoxication. Active detoxification at this, or an earlier stage, leaves the patient with a good chance of recovery. At a later stage, with the occurrence of oliguria, semi-coma or coma, and latent convulsive movement, recovery is less certain. There is no specific antidote for the toxic effects of lithium. Haemodialysis is the most effective treatment for acute lithium poisoning. For patients with impaired, or potentially impaired renal function, peritoneal dialysis may be an alternative, but less effective, treatment. Forced diuresis demands unimpaired renal function, and is little more effective than withdrawal of treatment, supplemented with correction of water and electrolyte balance. Sodium overloading is not recommended. Patients on lithium prophylaxis are treated on an outpatient basis. Prevention of intoxication depends on cooperation between patient and clinician, and possibly on the use of smaller, low risk dosages in most patients.

A total of 39 Holstein cattle were grazed in tracts of wild grassland on account of shortage in pasture grass. Twenty-nine cattle were affected and 26 of them died during a 21-day period. The main signs were depression, anorexia, ascites, and oliguria. There was elevated serum urea nitrogen and sugar and protein in the urine. Pathological examination revealed turbid swelling of the kidney, an increase in the amount of fluid in the body cavity, edema in the perirenal adipose tissue and hemorrhage in various visceral organs and tissues. Histologically, acute tubular necrosis in the kidney, hypoplasia of the erythroblast series in the bone marrow, atrophy and degeneration of the lymphatic tissue and focal necrosis of the liver were observed in many of the cattle. Among cows experimentally fed Narthecium asiaticum Maxim., Polygonum sachalinense Fr. Schum., and Vitis coignetiae Pulliat which were presumed to have been ingested in large amounts by grazing cattle in the field, the cows fed N. asiaticum revealed the clinical, biochemical and pathological changes similar to those noticed in naturally affected cattle. Cows fed P. sachalinense and V. coignetiae showed no distinct systemic symptoms except transient anorexia and hypothermia.

Twenty-seven adults with acute poststreptococcal glomerulonephritis were divided into two groups according to the severity of reduction in renal function: (1) 14 patients with mild depression of renal function, and (2) 13 patients with more severe renal insufficiency. In the first group the outcome was favourable, with complete clinical recovery in 11 patients. Only two patients in the second group have recovered. Five have died of renal failure and in six the chronic stage has developed. The most notable histopathological lesion observed in this group of patients was severe proliferative glomerulonephritis with a large number of epithelial crescents. According to the mode of development and time of onset of renal failure, these 13 patients could be divided into three sub-groups: (1) early renal failure without oliguria (three patients), (2) early renal failure with severe oliguria or anuria (three patients) and (3) delayed renal failure (seven patients).Although there are exceptions, the development of renal insufficiency in an adult patient suffering from acute glomerulonephritis is usually associated with a guarded prognosis.

The hepatotoxic and nephrotoxic effects of CBr4 were studied in male Sprague-Dawley rats following a single i.p. administration in a dose range of 25 to 125 microliter/kg to animals maintained for 15 days either on normal diet or a diet containing 10 ppm chlordecone (CD). At these doses, CBr4 did not cause hepatotoxic effects when given alone or in combination with prior exposure to CD. CBr4 caused renal dysfunction characterized by oliguria, aciduria and hypo-osmolality, and these effects were abolished by dietary CD pretreatment. In vitro incubation of renal cortical slices obtained from CBr4-treated animals revealed a significant depression of organic anion transport, i.e., decreased transport of p-aminohippurate (PAH). Organic cation transport was unaffected as judged by accumulation of tetraethylammonium (TEA). CBr4-induced renal dysfunction appeared unrelated to depressed PAH transport since CD pretreatment which abolished renal dysfunction failed to restore PAH transport. These results show that CD does not potentiate CBr4 hepatotoxicity and the nephrotoxic effects of this halomethane are abolished by prior exposure to CD.

In the present study 1 h of total occlusion of the left renal artery in conscious rats was chosen as experimental model of ischemic acute renal failure (ARF), while the contralateral kidney was left intact. Chronic high dietary sodium intake, acute isotonic saline infusion, or administration of saralasin did not protect from ARF. Furosemide, mannitol, and verapamil converted oliguric into non-oliguric ARF in 100%, 75%, and 60% of the animals, resp. Protection from oliguria and preservation of GFR inversely correlated with the depression of cortical ATP-concentration (control: 1.32 +/- 0.07 mumoles/g wet weight) 6 h after ischemia by 16%, 41%, and 58% in mannitol- and verapamil- treated rats and in untreated rats, resp. At this time, Na-K-ATPase enzyme activities in renal cortex and papilla were unaffected, while enzyme activity in outer medulla was suppressed from 15.4 +/- 1.4 to 9.4 +/- 1.0 mumoles Pi/mg protein h in all groups of animals. The results suggest that in this model of ARF renal ischemia not only affects cellular energy supply in renal cortex but also causes severe structural and functional impairment in the outer medulla, probably leading to tubular obstruction and depression of glomerular function. Pharmacological protection from ischemic oliguric ARF cannot be achieved by prior induction of high urine flow rates alone but depends on the degree of metabolic and functional reserve of the injured tubular epithelium.
