Bronchogenic carcinoma in Northern India.

A study of 336 patients with bronchogenic carcinoma was carried out in Chandigarh, Northern India. The findings suggest that its epidemiology differs in several respects from that in Western countries. Almost a third of all patients and 94.4% of the 54 women had never smoked. The peak frequency of bronchogenic carcinoma occurred between the ages of 51 and 60 years, 14.6% of the patients being aged less than 41 years. Of the 232 smokers and ex-smokers, 48.3% had smoked only cigarettes, 28.4% only bidis (made of naturally cured tobacco), 19.8% both cigarettes and bidis, and 3.4% hukkas. There was a clear association between duration of smoking and frequency of carcinoma. Tumours were classified in 287 (85%) of the patients. Squamous-cell carcinoma was relatively more frequent (32.4%) than any other tumour type and occurred almost exclusively in smokers. Adenocarcinoma was found in 13.2% of patients and was the most frequent tumour in non-smokers. No differences of histological type were found between cigarette smokers and bidi smokers.

A comparative randomized double-blind clinical trial of isoaminile citrate and chlophedianol hydrochloride as antitussive agents.

The efficacy and safety of a new centrally acting antitussive agent, isoaminile citrate, was compared with that of chlophedianol hydrochloride in a double-blind, randomized interpatient study. A total of 66 patients participated, two and four patients were lost to follow-up with isoaminile and chlophedianol, respectively. In the experimentally induced cough in 12 normal human subjects, isoaminile (40 mg) was as effective as chlophedianol (20 mg), but its duration of action was somewhat longer. One subject developed allergic skin rash with chlophedianol and was withdrawn from the study. In 60 patients with cough associated with chest diseases, isoaminile (40 mg, 3 x daily) was as effective as chlophedianol (20 mg, 3 x daily) in suppressing cough as judged from the 3-h and 24-h cough counts. The increase in PEFR at day 7 of treatment was somewhat more marked with chlophedianol as compared with isoaminile. None of the drugs interfered with the expectoration process. The side effects observed were few, mild in nature, and did not require a decrease in dose or withdrawal of treatment in any of the patients. Isoaminile citrate was concluded to be an effective and relatively safe antitussive agent. Isoaminile citrate, alpha(isopropyl)-alpha-(beta-dimethylaminoproyl) phenylacetonitrile citrate, is a centrally acting antitussive agent. In animal experiments this drug was as efficacious as codeine but was devoid of any respiratory depressant effect [Krause 1958, Kuroda et al. 1971]. This controlled double-randomized interpatient study was designed to test the comparative efficacy and safety of isoaminile and chlophedianol, another centrally acting antitussive, in humans.

A comparative randomized double-blind clinical trial of pivampicillin and ampicillin in lower respiratory tract infections.

The efficacy and safety of pivampicillin was compared with that of ampicillin in 52 patients suffering from lower respiratory tract infections. Equimolar doses of pivampicillin (350 mg) and ampicillin (250 mg) were administered three times daily for 15 days in identical code-labeled capsules. Each patient received only one drug in a random double-blind order. Clinical as well as objective assessment showed that pivampicillin was comparatively more effective and safer than ampicillin on both the 7th and 15th day of treatment. The reduction in the volume and purulence of sputum and in cough and dyspnea was more marked with pivampicillin. The overall success rate was higher and the side effects were fewer with pivampicillin.

Epididymal sperm reserves of the goat (Capra hircus).

Epididymal sperm reserves were determined in 6 sexually mature goats. The numbers of spermatozoa in the caput, corpus and cauda epididymidis were 1.90 +/- 0.16, 0.66 +/- 0.04 and 6.18 +/- 0.91 x 10(9) respectively and they represented 21.7, 7.5 and 70.8% respectively of the sperm reserve on that side. The total epididymal sperm reserve/male was about 17.5 x 10(9) spermatozoa.
