Curcumin is a traditionally used spice with a potential to treat various inflammatory diseases including arthritis. This study was aimed at observing curcumin’s effects on the histopathological progression and interleukin-1β (IL-1β) levels in collageninduced arthritis (CIA). Thirty male Sprague-Dawley rats (150+50 g) were divided into five random groups. A group was assigned as the normal control (CTRL), while the remaining were subcutaneously immunised with 150 μg of collagen emulsion on day 0. CTRL and CIA-Curcumin-d0 groups were supplemented daily with olive oil (1 ml/kg) and curcumin (110 mg/ml/kg) from day 0, respectively. The CIA-OV (negative control), CIA-Beta and CIA-Curcumin-d14 groups were given daily supplementation of olive oil (1 ml/kg), Betamethasone (0.5 mg/ml/kg), and curcumin (110 mg/ml/kg) from day 14, respectively. The daily oral supplementations continued until day 42. The study showed that CIA-Beta (**P<0.05) and CIACurcumin- d0 (**P=0.01) groups had significantly lower mean histological scores compared to CIA-OV, respectively. Serum IL-1β levels for CIA-Beta and CIACurcumin- d0 were not significantly raised on day 42 as to compared to day 0, and the mean increment of IL-1β levels from day 0 to day 42 were significantly lower (**P≤0.01) for all the CIA groups compared to CIA-OV. There was no significant difference in both mean histological scores and IL-1β levels of CIA-Curcumin-d0 compared to CIA-Beta. Early supplementation of curcumin could potentially minimise disease progression of CIA in rats.

To develop a mathematical model of the distribution and metabolism of rat corticotropin-releasing factor (rCRF), the time course of 125I-labelled rCRF in plasma was measured in male Sprague–Dawley rats (i) following a rapid injection of 24 ng rCRF/100 g body weight (BW), or (ii) following a rapid injection of 424 ng rCRF/100 g BW, or (iii) during an infusion at a rate ranging from 0.28 to0.73 ng rCRF∙min−1∙100 g BW−1. The comparison of the one-, two-, and three-compartment models shows that the two-pool structure fits better to the dynamics of CRF in plasma as measured in each rat. Following a rapid injection the decay curve occurs in a biphasic manner; the early phase of disappearance is 25 times faster than the late one. There is no significant difference between the estimates of the metabolic clearance rate following both amplitudes of injection (0.40 ± 0.06 and 0.48 ± 0.05 mL∙min−1∙100 g BW−1). The volume of the first pool, 16.8 ± 1.1 mL/100 g BW, is four times larger than the plasma volume. It would thus appear that CRF is rapidly distributed from plasma into several tissues which are represented in the first pool of the model. The mean residence time of every CRF molecule in the second compartment, from the moment of secretion to its elimination, is from three to four times longer than in the first one. It stays, on average, between 140 min and 3 h in the system before an irreversible exit. At steady state, the disposal rate represents only 3% of the CRF mass of the first compartment every minute. These results could explain the prolonged effects of CRF on pituitary-adrenocortical secretion.

COVID-19 epidemic caused serious concern around the world. Innate and adaptive immunity prevents   occurring acute infection. Immunomodulatory activity tests and increased leucocyte cells in rat have been carried out using honey (H) and royal jelly (RJ). This study aims to prove the combination of honey and royal jelly in increasing the leucocyte profile in male Sprague Dawley rats. This study used 28 rats divided into 7 groups, namely the negative control and positive, single dose group H  and single dose RJ  and the combination dose 1, dose 2, and dose 3, then on day the 8th and 11th rats were injected intraperitoneally with 2% sheep red blood cell antigen as much as 0.5 ml. Leucocyte profile were carried out on the 8th and 15th days. The results showed significant difference on leukocyte count (p = 0.000), but there was a decrease in the normal range on day 15th. The highest leucocyte count was showed on the honey and the combination 3 group. Leukocyte differential showed no significant difference (p> 0.05). The honey group and the dose combination 3 showed an increase in the number of segment neutrophils. The difference in lymphocyte reduction was seen between the honey and royal jelly group, with the dose combination 3, respectively. There are significant differences in granulocyte cells enhancement between the honey group and the dose combination 3. We concluded that single dose honey can be an immunomodulatory.  Dose combination 3 can be an alternative for further research for immunomodulatory supplement product.

Objective: To determine the differences of germinal epithelial testicular cell apoptosis in white Sprague Dawley strain rat that received combination of cisplatin and vitamin E compared to Sprague Dawley strain rat that received cisplatin only. Material & Methods:  Twenty four Sprague Dawley rats were divided into 4 groups randomly. Group 1 Negative Control (NC) was given an injection of 1 cc 0.9% normal saline intraperitoneally as a placebo, group 2 Positive Control (PC) was given 5 mg/kgBW cisplatin intraperitoneally, group 3 (P1) was given cisplatin injection 5 mg/kgBW intraperitoneally + vitamin E (α tocopherol) 50 mg/kgBW by gavage and group 4 (P2) was given cisplatin injection 5 mg/kgBW intraperitoneally + vitamin E (α tocopherol) 200 mg/kgBW by gavage. Vitamin E (α tocopherol) was given 3 weeks before up to 4 weeks after cisplatin injection. Observation of the germinal epithelial cells apoptosis was carried out by calculating germinal epithelial cells apoptosis in the cross-section preparations of the seminiferous tubule which gave a positive reaction to the apoptag staining, using a 400x magnification light microscope. Results: Apoptosis on positive control (PC) group was different significantly compared to the negative control (NC) group (p<0.05). There was a significant difference in the apoptosis of germinal epithelial testicular cells in the cisplatin + vitamin E 50 mg/kgBW compared to the PC group (p<0.05). The cisplatin + vitamin E 200 mg/kgBW group; had a lower number of apoptosis compared to the cisplatin + vitamin E 50 mg/kgBW (p<0.05). Conclusion: Vitamin E provides a protective effect on decreasing the amount of apoptosis due to cisplatin exposure. The protective effect of vitamin E is dose-dependent.

AbstractIntroduction: Wounds are a breakdown of tissue integrity / continuity that can lead to infection. Virgin Coconut Oil is a processed coconut product made by processing fresh coconut flesh at low temperature and has a high nutritional content. Ozone therapy is an alternative therapy that has disinfectant properties and can induce strong oxidative stress. Methods: This study was conducted on 50 Sprague-Dawley rats that had injuries. We performed full thickness wounds and administered ozonated doses of VCO to mice. We looked at shrinkage of wounds and TGF Beta levels in mice. Assessment was carried out on day 7 and day 14 to assess the wound and TGF-beta immunohistochemically. Results: There was a significant difference in the wound shrinkage variable between the negative control group and the group that received VCO offerings both on day 7 and day 14. We also found a significant difference in the TGF-beta variable between the negative control group and the group that received VCO offerings both on day 7 and day 14. Conclusion: The administration of ozonated virgin coconut oil was effective in increasing the expression of TGF-? in the full thickness defect of Sprague Dawley rats and was effective in increasing the reduction in wound size in the full thickness defect of Sprague Dawley rats.

Conventionally, the strength of toe plantar flexion (STPF) is measured in a seated position, in which not only the target toe joints but also the knee and particularly ankle joints, are usually restrained. We have developed an approach for the measurement of STPF which does not involve restraint and considers the interactions of adjacent joints of the lower extremities. This study aimed to evaluate this new approach and comparing with the seated approach. A thin, light-weight, rigid plate was attached to the sole of the foot in order to immobilize the toe area. Participants were 13 healthy young women (mean age: 24 ± 4 years). For measurement of STPF with the new approach, participants were instructed to stand, raise the device-wearing leg slightly, plantar flex the ankle, and push the sensor sheet with the toes to exert STPF. The sensor sheet of the F-scan II system was inserted between the foot sole and the plate. For measurement with the seated approach, participants were instructed to sit and push the sensor with the toes. They were required to maintain the hip, knee, and ankle joints at 90°. The mean values of maximum STPF of the 13 participants obtained with each approach were compared. There was no significant difference in mean value of maximum STPF when the two approaches were compared (new: 59 ± 23 N, seated: 47 ± 33 N). The coefficient of variation of maximum STPF was smaller for data obtained with the new approach (new: 39%, seated: 70%). Our simple approach enables measurement of STPF without the need for the restraints that are required for the conventional seated approach. These results suggest that the new approach is a valid method for measurement of STPF.

Forty-eight crossbred pigs of average initial weight 21 kg were fed 10% Tower rapeseed meal (RSM) and 10% Candle RSM as partial replacements for soybean meal (SBM). Diets were formulated to be isocaloric. Pigs fed the SBM diet consumed less feed, gained significantly (P < 0.01) faster and were more efficient at converting feed to gain than those fed the RSM diets. Performance of pigs fed Candle RSM was not significantly different to that obtained with Tower RSM. In a second experiment, dehulled Tower RSM and Tower RSM hulls were mixed in amounts to produce RSM with crude fibre levels of 6.8, 10.8, 13.5 and 15.8%. The simulated RSM and Tower and Candle RSM were used to completely replace SBM in the diets of weanling (75 g) Sprague-Dawley rats. Rats fed SBM had significantly (P < 0.05) higher average daily gain (ADG) than those fed Tower or Candle RSM, or diets containing the rapeseed meats. There was no significant (P < 0.05) difference in ADG, feed intake or feed to gain ratio of rats fed either Tower or Candle RSM. Feed intake, feed to gain ratio and fecal volatile fatty acid concentrations increased while average daily gain decreased with increasing level of hulls in simulated RSM diets. There was no significant difference (P < 0.05) in thyroid weight between rats fed SBM, Tower RSM or Candle RSM.

Methanol poisoning is a hazardous intoxication characterized by visual impairment and formic acidemia. The therapy for methanol poisoning is alcohol dehydrogenase (ADH) inhibitors to prevent formate accumulation. Ranitidine has been considered to be an inhibitor of both gastric alcohol and hepatic aldehyde dehydrogenase enzymes. This study aimed at testing ranitidine as an antidote for methanol acute toxicity and comparing it with ethanol and 4-methyl pyrazole (4-MP). This study was conducted on 48 Sprague-Dawley rats, divided into 6 groups, with 8 rats in each group (one negative control group [C1], two positive control groups [C2, C3] and three test groups [1, 2 and 3]). C2, C3 and all test groups were exposed to nitrous oxide by inhalation, then, C3 group was given methanol (3 g/kg orally). The three test groups 1, 2 and 3 were given ethanol (0.5 g/kg orally), 4-MP (15 mg/kg intraperitoneally) and ranitidine (30 mg/kg intraperitoneally), respectively, 4 hours after giving methanol. Rats were sacrificed and heparinized, cardiac blood samples were collected for blood pH and bicarbonate. Non-heparinized blood samples were collected for formate levels by high performance liquid chromatography. Eye balls were enucleated for histological examination of the retina. Ranitidine corrected metabolic acidosis (p = .025), decreased formate levels (p = .014) and improved the histological findings in the retina induced by acute methanol toxicity.

Abstract. Aflatoxin B1 (AFB1) is a toxic compound commonly found in some crops with an adverse health effect on human and animals. Some beneficial microorganisms (or probiotics) such as lactic acid bacteria have shown the ability to reduce the bioavailability of aflatoxins and its intestinal absorption. However, the dose and duration of aflatoxins exposure and probiotic treatment can influence the ability of probiotics to remove aflatoxins. Therefore, this research aimed to investigate the efficacy of oral probiotic Lactobacillus casei Shirota strain (LcS) induction in an acute exposure to AFB1 in rats. Experimentally, Sprague Dawley rats were divided into three groups: AFB1 only (n = 9); AFB1 treated with LcS (n = 9); and control (no AFB1 exposure) (n = 6) groups. The blood AFB1 level of rats treated with LcS was slightly lower than the untreated AFB1 induced rats (11.12 ± 0.71 vs 10.93 ± 0.69 ng g–1). Also, LcS treatment slightly moderated the liver and kidney biomarkers in AFB1 induced rats. However, a trend for a significant difference was only observed in ALT of AFB1 induced rats treated with LcS compared to their counterparts (126.11 ± 36.90 vs 157.36 ± 15.46, p = 0.06). Rats’ body weight decreased in all animals force-fed with AFB1 with no significant difference between LcS treatment compared to the counterpart. In conclusion, this experiment indicated that probiotic LsC was able to slightly ameliorate the adverse effect of an acute exposure to AFB1 in rats. However, future studies with longer probiotics treatment or higher probiotics dose is required to confirm these findings.

ABSTRACT Background: Infertility may give an impact on psychosocial. In Indonesia, the habit of consuming young dates is often done by couples to increase fertility. FSH is one of the factors that play a role in folliculogenesis. The lack of scientific evidence of young dates consumption effects on female reproduction has led to this study. This study aims to determine the levels of FSH hormone and the picture of ovarian tissue in mice after administration of young dates. Method: This study used an experimental design using 28 female Sprague-Dawley rats which were randomly divided into 4 groups. Group I to III was given young dates in successive doses: 17 mg, 34 mg, 68 mg per 200 grams of body weight and group IV was given distilled water. The treatment was carried out for 28 days. FSH levels were examined before treatment during the proestrus phase which was known from microscopic examination of rat vaginal swabs. The treatment begins during the proestrus phase. Result: The mean baseline and post-treatment FSH levels were 0.08 and 0.09 respectively Conclusion: There is no significant increase of FSH levels and FSH receptors as the effect of giving young dates (Phoenix Dactylifera) to female Sprague-Dawley rats Keywords: Dates, FSH, FSH receptors, Rats   ABSTRAK Latar Belakang: Infertilitas dapat memberikan dampak psikososial.
