The ability of a pituitary extract to induce ovulation and the effect of multiple ovulations on pregnancy rate and incidence of multiple fetuses were studied in seasonally anovulatory mares. The ...extract induced ovulation in 95% of mares having a greater than or equal to 25 mm follicle at the onset of treatment and in 64% the ovulations were multiple. The extract was less effective when the largest initial follicle was less than 25 mm. Approximately 50% of the treated mares that ovulated did not become pregnant or enter prolonged dioestrus before returning to an anovulatory condition. In treated mares with one ovulation the pregnancy rate (33%) was lower than in controls (60%) and was further reduced in mares with greater than 2 ovulations. There was a pronounced discrepancy between the number of palpated conceptuses and number of palpated ovulations. Only one conceptus and one fetus was found on Days 28 and 50, respectively, in every pregnant mare (11 treated, 1 control) in which multiple ovulations were palpated.
The first cases in the United States of swine infections caused by the fungus Microsporum nanum are reported. The infections occurred in a herd of Yorkshire swine in Pennsylvania. The dermatophyte, ...which readily produced experimental infections, was identified by isolation and studies in pure cultures.
The importance of the educational diagnosis in instructing patients in a fat modified diet was examined in a double blind study. The educational diagnosis depended upon the assessment of three ...independent instructional parameters: the amount of structure, the teaching mode, and the language code preferred by the patient. Group I (67 patients) received traditional personalized counseling for 3 months. Group IIa (40 patients), whose instruction was matched to their preferred educational attributes, was randomized against group IIb (36 patients), whose instruction was mismatched. Group IIIa (33 patients), receiving matched instruction was randomized against group IIIb (35 patients), receiving high structure in the symbolic mode of instruction. The greatest reduction in serum cholesterol was seen in group I. At 3 months, no significant difference in serum cholesterol reduction could be shown between groups IIa and IIb, or IIIa and IIIb. However, the mean cholesterol reduction became significantly greater (P < 0.05) in IIa than IIb at the 6 month visit. Seven day food diaries showed no significant differences in dietary intake at 1 and 3 months between matched and unmatched groups. The data did suggest that patients preferring high structure in the symbolic mode had a greater serum cholesterol reduction than other diagnostic groups. Analysis of variance showed an interaction between the preferred and instructional level of structure as related to the change in total calories, total fat, and saturated fat of the diet after 3 months.

Journal Article
A method is described for the determination of gamma-aminobutyric acid (GABA) levels in human cerebrospinal fluid by modification of the radioreceptor assay utilizing 3Hmuscimol as labelled ligand. ...This method is compared with the radioreceptor assay using 3HGABA as labelled ligand. Although the 3Hmuscimol assay is less sensitive than the 3HGABA method, it offers the advantage of being more rapid due to the use of a filtration step instead of the usual, more time-consuming centrifugation of the samples. Samples of CSF of patients with various neurological or psychiatric disturbances were analysed. There was a satisfactory correlation between the GABA values obtained by the two assays.
