Two new laboratory diagnostic tests for chronic glomerulonephritis and pyelonephritis have been developed. The first one is based on electrophoretic mobility of urinary lysozyme under certain conditions, such as the use of 12% polyacrylamide gel with pH of 4.3 and acid electrode buffer with pH of 4.0. After electrophoresis was discontinued, lysozyme position was determined by lysis of Micrococcus lysodeikticus, used as test agents and added to the gel as a suspension prior to polymerization. Urinary lysozyme was found to be in the anode area of the gel in 95% of patients with chronic pyelonephritis, and in its cathode area in 92% of patients with chronic glomerulonephritis. There was no lysozyme in the urine of normal subjects. The other laboratory technique, the ethanol test, is based on comparative assessment of the degree of urinary opacification after ethanol is added in conditions of neutral reaction (following the addition of physiologic saline) and marked alkaline reaction (following the addition of sodium hydroxide solution). The ratio of optic density of the alkaline specimen to that of the neutral specimen was above 1 in patients with chronic glomerulonephritis, and below 1 in patients with chronic pyelonephritis and normal subjects. Examination of biochemical mechanisms of the proposed tests has demonstrated that the pattern of proteinuria is the most important factor affecting the results.

An enhanced frequency and morbidity of urinary tract infections (UTI) have been observed in association with alcoholism and liver disease. The causes of these phenomena may relate, in part, to the defects in humoral and cellular immune mechanisms that occur in alcoholism. Urinary catheterization is the most common cause of UTI in hospitalized alcoholics. The severity of the sequelae of UTI in alcoholism is demonstrated by the unusually frequent occurrence of renal papillary necrosis (RPN) in conjunction with pyelonephritis in these patients. Indeed, in over 90% of the reported cases of RPN occurring with alcoholism or liver disease, pyelonephritis has been a contributing factor. The proclivity to medullary ischemia and RPN in this patient group may be, at least in part, a result of interstitial renal edema secondary both to infection and the effect of ethanol per se and to renal arterial vasoconstriction that occurs in cirrhosis. The frequency with which death due to sepsis or renal failure occurs in association with UTI in alcoholics obliges the physician to exercise caution in the prevention and treatment of UTI in these patients.

Distilled water containing 40 micrograms/ml peplomycin and 2% ethanol was used as a perfusate in 8 patients with superficial bladder tumors and 2 with deep bladder tumors for 2 hours at 43 degrees C. In addition, immediately before the perfusion treatment, 5 mg of peplomycin was injected intramuscularly. Prior to treatment, the nature and extent of the tumors were determined by ultrasonography, cystoscopy and cystography. The therapeutic effect of the hyperthermic perfusion was evaluated by the same manner as used previously. Partial tumor regression was obtained in 6 of the 8 patients with superficial bladder tumors. The 2 patients with deep bladder tumors showed no tumor regression. Most of the patients had bladder discomfort such as irritation, pollakisuria and so on, during and/or after perfusion. No patient developed acute pyelonephritis.

We studied the nutritional and metabolic features of Eubacterium suis, an anaerobic animal pathogen that causes cystitis and pyelonephritis in pigs. Peptone-yeast extract-starch (PYS) medium, which contained Trypticase (BBL Microbiology Systems), yeast extract, starch, minerals, cysteine, and sodium carbonate, was shown to support excellent growth of this organism (absorbance at 600 nm = 1.8). Growth was considerably less (absorbance at 600 nm = 0.6) when the starch in the medium was replaced by maltose. Formate, acetate, and ethanol were the major products of fermentation of starch or maltose. The organism appears to require a fermentable carbohydrate for growth since the deletion of starch from PYS resulted in a negligible amount of growth. Growth decreased by approximately 20% when CO2 was rigorously excluded from PYS minus Na2CO3. The deletion of only yeast extract from PYS resulted in a decrease in growth of about 75%, and the simultaneous deletion of both yeast extract and Trypticase resulted in negligible growth. When the yeast extract in PYS was replaced by a defined mixture of purine and pyrimidine bases, vitamins, and amino acids, growth was greater than or equal to 80% that observed in PYS. The deletion of Trypticase from this medium resulted in no detectable growth, suggesting a possible peptide requirement for E. suis growth. Good growth (absorbance at 600 nm = 1.4) was obtained when adenine and uracil were substituted for the mixture of purine and pyrimidine bases in modified PYS; the substitution of pyridoxal, riboflavin, and nicotinic acid for the vitamin mixture gave comparable growth. The nutritional requirement of E. suis apparently reflect the fact that the organism adapts to its natural niche by doing away with certain biosynthetic capabilities which it does not seem to require.

Chronic alcoholism is accompanied by systemic involvement of the internal organs. Clinico-morphological forms of chronic alcoholism are distinguished on the basis of the prevailing organ pathology, Morphological data are presented, and pathogenesis of the lesions of the liver, heart, pancreas, and kidneys in patients with chronic alcoholism is analysed. The hepatic form may present alcoholic dystrophy, hepatitis or cirrhosis which are stages of progressing hepatopathy. The toxic and metabolic effect of ethanol is important in the pathogenesis of liver lesion. The cardiac form is characterized by the development of alcoholic myocardiodystrophy. In addition to the toxic influence of ethanol, hormonal and electrolyte changes and microcirculatory disorders play a role in its pathogenesis. Chronic calcifying pancreatitis in chronic alcoholism is associated with the effect of ethanol on the mediatory system. The renal form any present necronephrosis, hepatorenal syndrome, glomerulonephritis or pyelonephritis. Their pathogenesis is determined by toxicity of ethanol, circulation of immune complexes in the blood, or immunosuppression.
