Human spinal arachnoid villi and granulations

A commercially available recording of Northwestern University Auditory Test No. 6 (N.U. No. 6) produced by Auditec of St. Louis was evaluated in a series of four studies. Interlist equivalence of this version was initially investigated, and then normative intelligibility functions were developed using listerners with normal hearing. Intelligibility functions for the original version of N.U. No. 6. prepared by Northwestern University, were then derived, concurrently with functions of the Auditec version, using (1) a group of listeners with normal hearing; and (2) a group with sensorineural hearing loss. The results demonstrated good interlist equivalence for the Auditec version of N.U. No. 6. The comparative intelligibility functions for the Auditec and Northwestern versions of N.U. No 6 furthermore indicated a difference between the two recordings, but it was concluded that for clinical purposes the two versions may be considered equivalent.     

Hemodynamic responses to stellate ganglion stimulation in mongrels and greyhounds

A comparison of the effects of left stellate ganglion stimulation (SGS) on central and aortic hemodynamics has been made in chloralose-anesthetized mongrel (M), and greyhound (GH) dogs. Measurements of aortic pressure and flow, and left ventricular pressure were made during stimulation of the decentralized left SG at different frequencies from 0 to 20 Hz. The increases in aortic pressure and flow with SGS were larger in the GH, especially for low frequencies of stimulation. Stroke volume was increased with SGS in the GH at all stimulation rates, whereas in the M it was unchanged. A greater decrease in left ventricular end-diastolic pressure with SGS was found in the GH. These results suggest that differences exist in both the intrinsic and extrinsic control of cardiac output in the greyhound dog compared to the mongrel. These differences may be in part responsible for the elevated arterial blood pressure in the greyhound compared to the mongrel.     

A simple program which processes liquid scintillation counting data from samples containing both 125I and 3H under conditions of varying quench

A human study of the effects of topical nystatin (Mycostatin) therapy of oral candidiasis showed that effects of treatment were limited to the time in which the drug was used. Two weeks of therapy resulted in significant reduction in number of organisms and marked improvement in signs and symptoms of candidiasis. The condition recurred rapidly following cessation of treatment. No change in specific anticandida antibody in saliva or in adherence of Candida albicans to mucosal epithelium (in vitro) was seen with treatment.     

Impact of breast cancer on Asian American and Anglo American women

This pilot study constitutes the first exploration of the impact of breast cancer on Asian American women. Three hypotheses guided this study: (1) Asian American women would choose breast conserving therapy and breast reconstruction at a lower rate than the Anglo American women due to cultural differences in body image, (2) Asian American women with breast cancer would express psychological distress somatically and Anglo American women would express distress emotionally, and acculturation levels of the Asian American women would modify the expressions of distress such that women with high acculturation will express distress more emotionally and less acculturated women would express distress more somatically, and (3) Asian American women would seek assistance for psychosocial problems at a significantly lower rate than Anglo women. Ethnicity, age, and levels of acculturation were found to be significant variables that had to be considered simultaneously. The three hypotheses were only partially supported: (1) Asian American women chose breast conserving therapy and adjuvant therapy at a significantly lower rate than the Anglo American women, (2) Contrary to the hypothesis, somatization did not appear to be a dominant form of symptom presentation for Asian American women regardless of level of acculturation, and (3) Asian American women sought professional assistance for psychosocial problems at a significantly lower rate than Anglo women. Asian American women reported using different modes of help-seeking behavior for emotional concerns and receiving different sources of social support than the Anglo American women. Cultural interpretations of the findings are offered to explain the differences in the physical, emotional, and social responses to the breast cancer experience of Asian American women compared with the Anglo Americans, and notably between the Chinese- and Japanese Americans as well. The findings of this study warrant more refined exploration in order to improve the medical, psychological and social outcomes for Asian American women with breast cancer.
