Purpose: To investigate casein's role in the expressions of human beta-defensin (HBD)-1, T helper subset (Th)-17, and interleukin (IL)-22 in preterm Rattus norvegicus (RNs). Methods: Twenty-four healthy, first-time pregnant RNs were divided into three groups (G). Group 1 (G1) received regular casein (R) 0.4 g/RN/day, while G2 and G3 received casein supplementation (S) 2 g/RN/day. Each RN was given 10 g of food and drank 10 mL. On day 10, a single intraperitoneal lipopolysaccharide (LPS) was injected with 100 g/kg body weight. Lipopolysaccharide was injected into G3 as a premature model with chorioamnionitis. Histopathological examination was carried out to measure the expression of HBD-1, Th-17, and IL-22 using methyl green counterstaining. Chorioamnion specimens were taken and fixed in 4 % paraformaldehyde, and then evaluated by immunohistochemical (IHC) procedures to obtain immunoreactive score (IMS). Results: The IMS expression of HBD-1 in G1 was 1.187 ± 0.372, while G3 was 9.562 ± 2.351 (p < 0.05). Th-17 expression were G1: 2.062 ± 0.140, G2: 6.122 ± 1.347, and G3: 9.112 ± 2.019 (p < 0.05). Furthermore, IL-22 expressions were G1: 1.825 ± 0.468, G2: 4.700 ± 1.614, and G3: 7.800 ± 1.669 (p < 0.05). Conclusion: Casein supplementation increases HBD-1, Th-17, and IL-22 expression in preterm RN and in the LPS-induced RN chorioamnionitis model. The increase in HBD-1, Th-17, and IL-22 indicate that casein plays a role in the protection and control of chorioamnionitis tissue inflammation. [ABSTRACT FROM AUTHOR]

Rhodamine B is a textile dye compounds containing chlorine (Cl-), alkylating (CH3-CH3), Poly Aromatic Hydrocarbons (PAH) which activate the enzyme cytochrome P-450 as well as the structure of quinone which is very redox that leads to the formation of Reactive Oxygen Species (ROS). ROS increases induce apoptosis of the intrinsic pathway. The imbalance ratio between BAX and BCL-2 stimulates apoptosis in Hippocampus tissue. "The selected design was "the post test only control group" using twenty-eight Wistar female Rattus norvegicus mouse age of 10-12 weeks. There was a significant difference (p-value <0.05) of total BCL-2 expression between the control group to the treatment group. Correlation coefficient of 0.945 indicates that the level of the relationship/ correlation is very strong category. Increasing doses of Rhodamine B was given, accompanied by the decrease in the expression of BCL-2. Correlation coefficient of -0.731 indicates that the level of the relationship/ correlation belongs strong category. It is concluded that Rhodamin B has been verified as capable to increase the expression of BAX and to reduce the expression of BCL-2 in hippocampus tissue on Rattus norvegicus.

Objective: The aim of this study was to observe the effects of ethanolic extract of Moringa oleifera varietas West Nusa Tenggara leaves on malondialdehyde (MDA) level and histological placental labyrinth zone of pregnant Rattus norvegicus exposed to cigarette smoke. Materials and Methods: This was an experimental study with post-test only control group design. Twenty pregnant R. norvegicus were randomly divided into five groups, namely negative control (-), positive control (+), and treatment of ethanolic extract of M. oleifera of 25 mg/kg BB/day (P1), 50 mg/kg BB/day (P2), and 100 mg/kg BB/day (P3). Results: This study showed an ethanolic extract of M. oleifera which showed significant effects on MDA level (P < 0.05). There was no significant effect of ethanolic extract of M. oleifera in various dose on placental labyrinth zone (P > 0.05). Conclusion: Ethanolic extract of M. oleifera decreased MDA level with optimal dose 25 mg/kg BB/day, but no significant effect on placental labyrinth zone of pregnant rats exposed to cigarette smoke at 14 days of pregnancy.
