The analgesic and hypothermic effects of nefopam, morphine, aspirin, diphenhydramine, and placebo.

One hundred and ninety-six hospitalized patients were randomly assigned to one of eight treatment groups consisting of oral or intramuscular analgesics and placebo. Patients were monitored for 6 hours for pain relief, vital signs, and side effects. No statistically significant differences in pain intensity or relief were seen for nefopam (Acupan), diphenhydramine (Benadryl), aspirin, or placebo despite a numerically higher score for nefopam.

Study of the venous drainage of the thyroid gland in dogs (Canis familiaris).

The authors studied the venous drainage of the thyroid gland in about 30 adult dogs without specific race of both sexes. The study was conducted using Neoprene Latex previously stained with specific pigment injected into cervical venous system, following, after fixation, dissection with disarmed eye or under dissecting microscope (10x). When necessary the cases observed showed 90% more than one venous branch in each glandular pole: 70% one ima thyroid vein and 70% one thyroid venous arch (laringeal); about 50% of dissecting cases drainage exclusively the thyroid gland, whereas the others 50% are responsible for the drainage of surrounding structures.

[Morphology of the epithelial cells of the epididymal duct of the south american oppossum (Didelphis azarae) (author's transl)].

5 cellular types were identified in the epithelium lining the epididymal duct of the opossum (Didelphis azarae): principal cells, clear, basal, apical and intraepithelial lymphocytes, similar to the epididymal duct of the rat. Morphological aspects of these cells are described in the present paper, at the optical microscope level.

Arterial pattern of the spleen in the domestic fowl.

The authors describe the variations on the origin, number and vascularization areas of the splenic artery of 50 fowls, 34 males and 16 females, Gallus gallus, Indian River, of different ages, with medium weight of 2.133 g. The results were expressed in relative percentage figures and compared with the literature cited.

New peroxides and their antimicrobial activity.

Antimicrobial activity of hydroperoxides and cyclic peroxides has been studied. 2,4-Dihydroperoxy-2,4-dimethylpentane (1) and 2,5-dihydroperoxy-2,5-dimethylhexane (2) were active against microorganism, but 1 showed a large specially against C. albicans, M.
