As a consequence of Isoniazid (INH) consumption in longterm is the damage on the liver cells which is detected in high level of SGPT and SGOT in blood. Unripe pineapple fruits contained higher level of phenolic acid and flavonoids compounds than the ripe pineapple fruits, and as a result the unripe pineapple fruits juice has higher hepatoprotective potency  than ripe pineapple fruits juice. The hepatoprotective activity of  unripe pineapple fruits juice was determined by measuring the SGPT and SGOT level on rat blood. There were prepared 24 rats, divided into 6 groups, i.e. normal control group, positive control group, negative control group, and 3 test goups that were induced  by INH and each was given the unripe pineapple fruits juice at 1 hour before and 1 hour after INH induction, with the dose of 2 mL and 4 mL. Treatment was conducted in 14 days, consecutively. To each of the rat groups, blood was taken out through the eye orbital sinus, i.e. on the first day, on the hour-0 and hour-3, and then the SGPT and SGOT level were measured. Later on, blood were taken out on the day-4, day-7, and day-14. On the rat blood that were taken out, were analyzed descriptively and statistically to determined the optimum dose and the time of the unripe pineapple fruits juice feeding in related with a hepatoprotective potency. Result showed that feeding of the unripe pineapple fruit juice 1 hour after INH induction with the dose of 2 mL during 14 days has the best hepatoprotective activity.

Programmed cell death ligand 1(PDL-1) is known for its inhibitory effect on the cellular immune response. Even though it is expressed on the surface of mast cells, its role in allergic diseases is unknown. We analyzed the effects of PD-L1 blockade in a murine model of active cutaneous anaphylaxis (ACA). C57BL/6 mice were sensitized and challenged with ovalbumin (OVA). Blood samples were collected to measure specific immunoglobulins. The mice were divided into six groups that underwent the active cutaneous anaphylaxis procedure. Group 1 (negative control) received 50 μl of phosphate-buffered saline (PBS) subcutaneously, and the other five groups were sensitized with 50 μg of OVA subcutaneously. Group 2 was the positive control, and the others received the anti-PD-L1 antibody or its isotype during sensitization (groups 3 and 4) or during the challenge (groups 5 and 6). All animals that underwent ACA on the ears with OVA and PBS were sacrificed, and the reaction was evaluated by extravasation of Evans blue (measured by spectrophotometry) and histological analysis of the collected fragments. Anti-PD-L1 blockade during the sensitization phase led to a reduction in specific IgE and IgG1 levels, allergic reaction intensity at the ACA site, and mast cell degranulation in the tissue. There was no significant biological effect of anti-PD-L1 administration on the challenge phase. PD-L1 blockade during allergen sensitization inhibited the synthesis of specific IgE and IgG1 and decreased mast cell activation in this murine model of anaphylaxis.

The aim of the study was to objectively evaluate the short-term effect of Arabic coffee and black tea on oral halitosis. This study was a single-center, randomized, double-blind, placebo-controlled, crossover clinical trial on 17 healthy individuals. During the initial visit, pre-treatment breath samples were collected from each subject and analyzed using portable gas chromatography (OralChroma™). Four interventions were evaluated, with Arabic coffee and black tea as the test intervention tools, mouthwash containing a solution (0.05% chlorhexidine, 0.05% cetylpyridinium chloride, and 0.14% zinc lactate (CHX-CPC-Zn)) as a positive control, and drinking water as a negative control. Halitosis was induced by rinsing with 10 mL solution of L-cysteine for 30 s. Twenty minutes later, a breath sample was taken to record the baseline volatile sulfur compounds (VSC) levels (T0). Then, the participants were asked to rinse with 10 mL of a randomly-assigned solution for 30 s. Sixty minutes later, another breath sample was recorded (T1). Finally, after 120 min, the final breath sample was recorded (T2). It was found that rinsing with Arabic coffee decreased the level of H2S both in the first hour (T1) and the second hour (T2). The reduction was significantly greater at T1 (p = 0.017). There was a similar result after the volunteers rinsed with black tea. At T2, Arabic coffee showed a substantially greater reduction in H2S (p < 0.001). On the contrary, using CHX-CPC-Zn showed a significant and continuous decrease in H2S values in the breath throughout the experiment (p < 0.001). Water showed no significant impact on the level of VSC (p = 0.71). This study demonstrates that black tea and Arabic coffee had inhibitory effects on halitosis that was greater in the first hour and was not sustained over a long period. Additionally, Arabic coffee had a greater inhibitory effect on halitosis than black tea.

Three prenylated xanthones, garcinone E (1), bannaxanthone D (2) and bannanxanthone E (3) were isolated from the leaves of Garcinia mckeaniana Graib. Their structures were elucidated by spectral methods and compared with literature data. To evaluate their anti-proliferative effects in tumor cells, firstly, cisplatin was used as a positive control and the effects of compound 1-3 were determined by performing MTT assay in MDA-MB-231, CNE-2 and A549 cancer cells. The results showed compound 1-3 exhibited stronger inhibitory effect than cisplatin in MDA-MB-231. Further effects of compound 1-3 in TNBC MDA-MB-231 and MDA-MB-468 cells were examined by performing cell cycle and apoptosis assays. The results indicated that compound 1-3 had ability to arrest cell cycle at G2/M phase and induce apoptosis. Furthermore, compound 2 significantly down-regulated PI3K, Akt and mTOR levels in both total proteins and phosphorylated form, which is its potential anti-cancer mechanism. These findings indicated that those prenylated xanthones might serve as promising leading compounds for the development of anticancer drug for TNBC.
