The purpose of this research was to know the influence of dipping time in natural methyl testosterone hormone (MT) on successful male forming process of tilapia (Oreochromis niloticus) larvae. This research used 360 7 days old tilapia larvae, purchased from cultivation of brackish water, Ujung Batee, Banda Aceh. The samples were divided into 4 treatment groups with three repetitions, they were P0 (control group without treatment), PII (Tilapia larvae were dipped in natural MT for 10 hours), PII (Tilapia larvae were dipped in natural MT for 20 hours), and PIII (Tilapia larvae were dipped in natural MT for 30 hours). All tilapia larvae were maintained until the age of 60 days, before the sex of the fish examined. The average percentage of male tilapia in group P0, PI, PII, and PIII were 50.28, 87.77, 90.06, and 95.05%, respectively. Statistical analysis showed that there were significant differences (P0.05) among P0, PI, PII, and PIII. Based on result of this research, it can be concluded that the longest dipping time the highest the percentage of male tilapia.Key words: larvae, tilapia, natural hormone methyl testosterone, the male sex percentage

Herbal medicine, including moringa (Moringa oleifera), is widely used as dietary supplementation to enhance growth performance and increase disease resistance in aquaculture. This study aimed to investigate the effects of supplementing moringa leaves on growth performance, hematology and disease resistance of nile tilapia (Oreochromis niloticus) against Aeromonas hydrophila. Fish (38.05 ± 0.83 g) were fed with a commercial feed supplemented by moringa leaves at 0%, 15%, 20%, and 25%, ad libitum, twice a day for eight weeks. Results revealed that 15% moringa leaves supplemented diet gave the highest weight gain, while the specific growth rate was statistically significantly different (p<0.05) among the treatments. Fish fed with 25% supplementation had the highest total red blood cell count and total white blood cell count. All experimental groups had higher values of red blood cells and white blood cells than the control group. The challenge test with A. hydrophila showed that the fish fed with the 25% moringa leaves supplementation diet had the highest relative percentage survival rate. There were no significant differences among the treatment groups. However, the treatment groups had a statistically significant difference with the control group (p<0.05). Results of the present study indicated that supplementation of 15% moringa leaves in diet gave optimal growth performance, while supplementation of 25% moringa leaves in the diet showed the best results in terms of the health of nile tilapia. Moringa leaves supplemented in nile tilapia diet enhanced growth performance and increased disease resistance against A. hydrophila.

Цель исследования - изучение перепрограммирования мононуклеарных лейкоцитов на модели системного ювенильного идиопатического артрита (сЮИА), воспроизводимой у крыс Wistar с использованием полного адъюванта Фрейнда и липополисахарида. Методика. сЮИА воспроизведен у 6-месячных крыс-самцов Wistar. На 40-е сут. эксперимента животные были разделены на 3 группы: 1-я группа - контроль; 2-я - группа доксициклина; 3-я - группа дексаметазона. Взятие проб крови у животных проводили на нулевые, 41-е и 55-е сут. Мононуклеарные клетки периферической крови выделяли гравиметрически, после чего окрашивали их на маркеры и внутриклеточные цитокины. Дифференцировали моноциты (CD3-CD4+) и Т-хелперы (CD3+CD4+). Анализировали динамику внутриклеточной экспрессии интерлейкина IL-4 (рассматривали как маркер про-М2 фенотипа, так как в случае выделения из клетки ИЛ-4 служит стимулятором М2 поляризации макрофагов) и IFN-g (как маркер про-М1 фенотипа) по данным проточной цитофлуориметрии. Применяли непараметрический статистический тест Mann-Whitney-Wilcoxon в программе R для статистической обработки данных. Результаты и заключение. При моделировании сЮИА выявлено закономерное изменение фенотипа моноцитов. Применение же доксициклина и дексаметазона приводило к более ранней поляризации их по про-М2-пути в отношении моноцитов (на 41-е сут.) в сравнении с контролем. Про-М1 эффект (на 55-е сут., в сравнении с контролем) выявлен также в группах доксициклина и дексаметазона. У животных разных групп обнаружены характерные динамические изменения внутриклеточной экспрессии цитокинов. Важно, что различная направленность поляризации фенотипа при сЮИА и применении препаратов наблюдается не только у моноцитов, но и у Т-хелперов. The study objective was to evaluate targeted reprogramming of peripheral blood mononuclear cells in systemic juvenile idiopathic arthritis (sJIA) modeled in 6-month-old male Wistar rats by co-administration of complete Freund’s adjuvant and lipopolysaccharide. Methods. On day 40 of the experiment, rats were divided into three groups: control, doxycycline, and dexamethasone groups. Blood samples were collected on days 0, 41, and 55. Peripheral blood mononuclear cells were isolated gravimetrically and stained for markers and cytokines. Monocytes (CD3-CD4+) and T-helpers (CD3+CD4+) were differentiated as target cells. IL-4 was considered a marker for the pro-M2 phenotype since IL-4 can activate M2 macrophage polarization; IFN-g was considered a marker for the pro-M1 phenotype. Time-related changes in the intracellular expression of IL-4 and IFN-g were studied using flow cytometry. Data were analyzed using nonparametric statistical tests (Mann-Whitney-Wilcoxon) in the R environment for statistical computing. Results and conclusions. Monocytes (like macrophages) underwent reprogramming during the development of modeled sJIA disease. In monocytes of doxycycline and dexamethasone treatment groups, pro-M2 effects were observed earlier (day 41) than in the control group. Pro-M1 effects were observed in monocytes of doxycycline and dexamethasone groups on day 55, as compared with the control group. Characteristic time-related changes of intracellular cytokine expression were described for different groups. Importantly, the differently directed phenotype polarization was observed in sJIA and treatment groups for both monocytes and T-helpers.
