The intestinal brush-border membrane vesicles (BBMVs) of Trematous bernachii were isolated to determine the mechanisms of nutrient adsorption and transport in Antarctic fish. Analysis of isolated Trematous bernachii BBMVs based on fluorescence changes and rapid filtration technique indicated a sodium-dependent intestinal nutrient transport mechanism. Furthermore, the intestinal cell membrane of Antarctic teleost also exhibited higher unsaturated/saturated fatty acid ratio compared to eel intestines.

Follow-up data (mean 9 months) were obtained for 74 subjects who had been treated for a mean of 8 months and 17 sessions in a controlled comparison of Behavioral vs Supportive Counselling for drug abuse. Based on urinalysis, self-report, and family report, all subjects (100%) were actively using drugs at pre-treatment. During the last month of treatment, 81% of the Supportive treatment subjects and 44% of the Behavioral treatment subjects were using drugs at least once. At the follow-up month, drugs were used at least once by 71% of the Supportive vs 42% of Behavioral subjects. When drug use was measured in terms of the number of days of use per month, Supportive counselled subjects did not decrease drug use either by the end of treatment or at follow-up; for Behavioral subjects, drug use decreased by 63% by the end of treatment and by 73% at follow-up. Alcohol use, and days worked/or in school showed a similar pattern of greater improvement for the Behavioral treatment being maintained at the follow-up. These results indicate a substantial treatment-specific reduction of drug usage that endures after treatment is discontinued. The present favorable results appear attributable to the inclusion of family/significant others in therapy and the use of reinforcement contingent on urinalysis results.
