A subacute toxicity study of propiverine hydrochloride (P-4), a new anti-pollakiuria agent, was carried out using male and female Wistar rats. P-4 was orally administered to rats at dose levels of 2, 10, 50 and 150 mg/kg/day for 13 weeks, followed by 5 weeks recovery period. The results obtained are as follows: 1. In the general conditions, transient salivation was observed immediately after administration and blotted fur at lower abdomen was noted in rats given 50 mg/kg/day or more. There were no deaths related to P-4. 2. Body weight gain was depressed in males given 50 mg/kg/day or more and females given 150 mg/kg/day. No significant changes in food consumption were observed. Water consumption increased in the groups of 50 mg/kg/day or more. 3. Urinalysis revealed an increase of urine volume, decreases of osmotic pressure, protein and urobilinogen, and a slight increase in excretion of electrolyte in rats given 50 mg/kg/day or more. 4. Hematological examinations revealed slight changes such as an increase in erythrocyte count and a shortening of APTT in rats given 150 mg/kg/day. 5. Serum biochemical examinations showed a decrease in triglyceride and increases in gamma-GTP and AlP activities, and urea nitrogen in males given 50 mg/kg/day or more and females given 150 mg/kg/day. Additionally, decreases in total and free cholesterol, and phospholipid for males and an increase of total cholesterol and a decrease of cholinesterase activity for females were detected. 6. At autopsy, atrophy of thymus and spleen was observed in rats given 50 mg/kg/day or more, but without histopathological correlation. Histopathological examinations revealed hypertrophy and fatty degeneration of hepatocytes, which were accompanied with increases of absolute and/or relative liver weight, in males given 50 mg/kg/day or more and females given 150 mg/kg/day. Electron-microscopy showed proliferation of smooth endoplasmic reticulum in the same groups. In the kidney, eosinophilic and intranuclear inclusions in the tubular epithelium were detected, in which cytoplasm there were no toxic injuries, in males given 10 mg/kg/day or more and females given 50 mg/kg/day or more. 7. After 5 weeks recovery period, above-mentioned changes were generally disappeared, suggesting that these were reversible. 8. The non-effective dose levels and the toxic dose levels of P-4 were estimated to be 2 mg/kg/day for males and 10 mg/kg/day for females, and 50 mg/kg/day for males and 150 mg/kg/day for females, respectively.

30 aged patients, with chronic urinary tract infections, were treated with a thymus extract (thymostimulin, TP-1 Serono), in combination with antibiotic therapy, according to the antibiogram data, or with antibiotic therapy alone. When thymus extracts were added to the treatment, an improvement of the clinical course of the disease was observed and the severity and duration of the subjective symptoms such as strangury, dysuria, and pollakiuria, were reduced. The two groups of patients presented no modifications of the febrile patterns, nor persistence in or recovery from infection after 30 days of treatment, but especially after 90 days, the frequency of reinfections or the persistence of infections were markedly reduced. During treatment with thymostimulin, there was an evident increase in the cellular immunity tests (T-lymphocytes, rosettes, PHA) as compared with the immunodepression found before treatment.

NS-21, (+/-)-4-diethylamino-1,1-dimethylbut-2-yn-1-yl 2-cyclohexyl-2-hydroxy-2-phenylacetate monohydrochloride monohydrate, is a new drug for the treatment of urinary frequency and incontinence. To evaluate acute toxicities of its related compounds including the optical isomers of NS-21 ((S)NS-21 and (R)NS-21), the active metabolite of NS-21 ((R/S)RCC-36), the optical isomers of (R/S)RCC-36 ((S)RCC-36 and (R)RCC-36), the hydrolysis products of NS-21 (RCC-32 and RCC-38) and the bi-product of NS-21 (RCC-66), single-dose intraperitoneal toxicity studies were conducted in ddY mice. The LD50 values of these compounds in male and female mice were as follows: 199 and 184 mg/kg for (S)NS-21, 261 and 240 mg/kg for (R)NS-21, 74 and 100-150 mg/kg for (R/S)RCC-36, 93 mg/kg for (S)RCC-36 in both sexes, 83 and 104 mg/kg for (R)RCC-36, higher than 510 mg/kg for RCC-32 in both sexes, 340-510 mg/kg for RCC-38 in both sexes, and 1000-2000 mg/kg for RCC-66 in both sexes, respectively. The clinical signs included decreased spontaneous locomotor activity, prone or lateral position, ataxic gait, clonic convulsion, hypopnea, hypothermia, pale skin, mydriasis, abdominal distention and unkempt fur for (S)NS-21, (R)NS-21, (R/S)RCC-36, (S)RCC-36 and (R)RCC-36, decreased spontaneous locomotor activity, prone position, ataxic gait, clonic convulsion, tail elevation and hypopnea for RCC-32 and RCC-38, and decreased spontaneous locomotor activity and unkempt fur for RCC-66. Body weight was decreased or its gain was suppressed for every compound examined. Pathological examination of the dead mice showed atrophy of the thymus and spleen, intestinal distention with the retention of dark red contents, white spots or white materials in the abdominal fatty tissue for (S)NS-21, (R)NS-21, (R/S)RCC-36, (S)RCC-36, (R)RCC-36 and RCC-66, but no treatment related change for RCC-32 and RCC-38. Adhesion between the abdominal organs was observed in survivors treated with (S)NS-21, (R)NS-21, (S)RCC-36, (R)RCC-36, RCC-32 and RCC-66.
