Parkinson's disease is one of the most common types of the neurodegenerative disease, which is characterized by the movement disorders such as slowness, lack of movement, muscle stiffness, and resting tremor, and hypophonic. The main reason of disease is the destruction of dopaminergic neurons in the Substantia Nigra in the midbrain and a decrease in dopamine concentration in the striatum terminals. In this study, used culture medium was DMEM with FBS, and the cells under study were catecholaminergic cells.6-Hydroxy dopamine toxin was used on cells to create a Parkinson cell model. Curcumin was used as a drug, and MTT, and BT methods were used to count the living cells. This research was designed to study the curcumin effect on Parkinson's disease with cellular model induced by 6-Hydroxy dopamine toxin with reduced inflammation. This study's results showed that using curcumin can increase the antioxidant power and protect the cell from damage caused by reactive oxygen species. Due to the results of MTT, and curcumin treatment due to its anti-inflammatory properties BT test also showed that cellular protection had increased, the death of aminergic catechol cells by 6-hydroxy dopamine toxin was significantly reduced. It shows the antioxidant and anti-inflammatory effects of curcumin on the damage caused by Parkinson's disease and reducing the progression of symptoms. Treatment withcurcumin to be anti-inflammatory can reduce the death of catecholaminergic cells by 6-hydroxy dopamine toxin.

Oxidative stress which is responsible for pathophysiology of hypertension, causes decrease in total antioxidant capacity. PON 1 is an antioxidant enzyme present on the surface of HDL also which is responsible for prevention of HTN and it’s complications. The aim of this study was to investigate the Effect of Isosorbide and Garlic Supplementation on Protein levels and Gene expression of PON1 at the Heart tissue in Female rats with hypertension After a period of aerobic training.

In the experimental study,30 female Wistar rats weighing 180-220 g were randomly divided into 8 groups: healthy control, sham, blood pressure induction (Hyper), garlic, endurance training, endurance training -garlic. The rats suffered from hypertension of 6 days a week for 8 weeks after dietary period and 10 mg/kg body weight L_NAME injection. Experimental groups received 50 mg/kg body weight garlic supplement for six weeks.The endurance training program was performed at speeds of 20-30 m/min and 20 to 35 minutes, 5 sessions per week for 6 weeks. Protein levels and expression of PON1 heart tissue were measured using ELISA kit and Real Time PCR. Data were analyzed by t-test, One-way ANOVA and post hoc tokey at the significant level P<0.05.

The results showed that there was no significant difference between the mean protein and the expression of paraoxonase-1 in the heart tissue of the female rats with hypertension in the different groups of the study (P> 0.05).Also, there was no difference between the levels of protein paraoxonase-1 heart tissue in different groups than the group of blood pressure induction (P> 0.05).

According to the findings, it seems to that the inadequacy of the training period (frequency and intensity of exercise) and the dose rate of Garlic Supplementation can be one of the possible causes of ineffectiveness in the present study.

Gastric ulcer or gastritis is a benign disease in the digestive system which is caused by a small ulcer in the inner lining and gastric mucosa. Among gastric ulcer characteristics is the deep ulcer that passes through the gastric mucosa. Almost all benign gastric ulcers are located in the anthrome (the lower stomach area). One of the methods to treat gastric ulcer is the use of medicinal herbs. Among effective medicinal herbs in treating gastric ulcer is Nigella sativa. The most important application of Nigella sativa is in inflammation reduction and wound healing acceleration. Substances such as linoleic oil, thymoquinone and antioxidants are obtained from nigella sativa. The rats were fed using a standard laboratory diet. Prior to surgery, the rats were deprived of food for 48 hours, and no water was given to them two hours before surgery. Gastric ulcer was generated by injecting acetic acid to stomach lining where there were no vessels. The oil at different doses was given to rats through gavage tube one day after gastric ulcer was generated. The rats were killed on days 4, 7, 10, and 14, and their stomachs were removed and the ulcer dimensions were calculated in terms of m2. Moreover, after cutting and providing lam, in order to conduct histological studies, samples were stained using hematoxylin and eosin and were examined by microscope. The obtained results showed that the percentage of wound healing in Nigella sativa at three doses (50, 100, 200 mg/kg) on days 4, 7, 10, and 14 had a significant increase in comparison to sham-operated and control groups (P<5%). Due to the presence of compounds such as terpenes, flavonoids, vitamins A, B, and C, and the anti-inflammatory and antioxidant properties in Nigella sativa, it facilitates the gastric ulcer healing, protects stomach tissue, and reduces gastric inflammation and ulcer, and has a greater restorative effect on gastric ulcer caused by acetic acid.

Parkinson's disease is one of the most common types of neurodegenerative diseases characterized by motor disorders such as slow motion, lack of movement, muscle stiffness, resting vibrations, and facial masks. The main cause of the disease is the destruction of dopaminergic neurons in the compact part of the substantia nigra in the middle cerebrum, which is associated with a decrease in dopamine concentration at the terminals of corpus striatum. This study was conducted to investigate the effect of coenzyme Q10 on the 6-hydroxydopamine-induced animal model (PD). To create a mock-up model of Parkinson's disease, 6-HDOP poison five μg/kg of mice body weight was injected into the Substantia nigra nucleus in adult NMRI mice. The accuracy of the Parkinson's model in mice was confirmed using catalepsy and apomorphine-induced rotation tests. Immediately after surgery, the Parkinsonian mice were treated with water (solvent Q10) with doses of 25, 50, and 100 Coenzyme Q10 for two weeks and then were subjected to behavioural tests and the neurons of the substantia nigra nucleus was counted. The results indicate that treatment with Q10 significantly reduced the immobility time and Catalepsy, increased motor activity and decreased apomorphine rotation, indicating the protective effects of Coenzyme Q10 against Parkinson's Disease Damage.
