Background: Since the time of stone age herbs in its natural forms are used for a variety of medicinal purposes including the treatment of pain. Research in herbal medicine is in a relatively early phase. Herbal approaches usually have been pursued because of the perception that these therapies are gentler and cause fewer side effects than allopathic treatment. The aim was to evaluate and compare the analgesic activity of essential oil of Rosmarinus officinalis and Thymus vulgaris in wistar rats.Methods: Wistar rats and hot plate method was used for this study. Control group (Group A) of 6 animals was given normal saline. Group B of 6 animals was given standard analgesic drug, aspirin (200mg/kg body weight). Group C of 6 rats was given REO at 100, 200, 300 and 400 mg/kg body weight on day 1, 2, 3 and 4 while Group D of 6 animals was given TEO at doses of 100, 200 and 300 mg/kg body wt. The analgesic activity of REO and TEO in terms of Response Time were noted and depicted in tabular form.Results: Results were analyzed by one-way-Anova and Tukey tests. Analgesic effect of Rosemary oil found to be statistically significant at all four doses, 100, 200, 300 and 400mg/kg body wt compared to control group. TEO was found significantly analgesic at 100 and 200mg/kg body wt compared to control group but at 300mg/kg body it was found lethal. REO was found superior.Conclusions: Analgesic effect of REO and TEO was not comparable to aspirin even at higher concentration like 400mg/kg (REO) but it was significantly more compare to control group.

 Objective: The objective of the study was to investigate the analgesic activity of hydroalcoholic extract of Murraya koenigii and Coriandrum sativum leaves and compared it with standard drug in an animal model.Methods: Hydroalcoholic extracts of M. koenigii and C. sativum leaves were obtained using Soxhlet apparatus. The central analgesic property was screened by hot plate method in mice and tail flick method in rats. The pain reaction time (PRT) was measured at 30, 60, and 120 min. The peripheral analgesic activity was evaluated by acetic acid induced writhing in mice.Results: In hot plate method M. koenigii leaves extract at both doses and tramadol showed significant increase in PRT at 30, 60, and 120 min compared with control group. C. sativum leaves extract showed significant increase in PRT only at 60 and 120 min compared to control group. In tail flick method M. koenigii leaves extract at both doses, higher dose of C. sativum leaves extract and tramadol showed significant increase in PRT at 30, 60, and 120 min compared with control group. Higher dose of M. koenigii leaves extract (200 mg/kg) was comparable with standard drug tramadol in both the methods. M. koenigii leaves extract at both dose showed significant reduction in the number of writhing but C. sativum leaves extract failed to show any significant reduction in the number of writhing compared with control. Higher dose of M. koenigii leaves extract was comparable with standard drug tramadol.Conclusion: M. koenigii leaves extract showed both peripheral and central analgesic effect while C. sativum leaves extract showed only peripheral analgesic effect.

Background: The extract of Corchorus olitorius has a reasonable content of vitamins A and C, calcium, iron and fibre, and therefore enjoys a universal application in the treatment of some disease conditions, even as the whole leaf is a very important component of food in so many cultures. Purpose: The study was designed to investigate the effect of Corchorus olitorius extracts on the testis of adult Wistar rats. Method: A total number of thirty two adult Wistar rats weighing between 180 and 200 grammes separated into four groups labeled A,B,C and D respectively were used for the study. Animals in group A which served as the control group were fed with the normal rat chow and water only. The group B rats were administered 100mg/kg body weight of aqueous extract of Corchorus olitorus; while those in group C were administered 500mg/kg body weight of the extract. The group D rats received 1000mg/kg body weight of the extract. For a period of four weeks, the different experimental animal groups received the respective aforementioned treatments once daily, around nine- o’clock in the morning through oral intubation. At the end of the 28 day treatment, the animals were sacrificed and the testes harvested for histological, investigation, and through cardiac puncture, blood samples for some hormonal studies was also collected and investigated using standard laboratory standards. Results: Observations made showed that the extract produced no histological distortions, degenerative or defective effects on the testicular tissues. The testosterone levels of group B, C, and D rats were observed to be significantly higher (P<0.005) than that of the group A (control group).ound: The extract of Corchorus olitorius has a reasonable content of vitamins A and C, calcium, iron and fibre, and therefore enjoys a universal application in the treatment of some disease conditions, even as the whole leaf is a very important component of food in so many cultures.

This experiment was conducted to determine the effect of papaya leaf (Carica papaya) and kalo jeera (Nigella sativa) seeds powdered supplementation in drinking water as a growth promoter in broiler chickens. A total of 20 Cobb-500 broiler chicks (day-old) were purchased from local hatchery (Nourish Poultry and Hatchery Ltd.) and after seven days of acclimatization chicks were randomly divided into two groups, A (n=10) and B (n=10). The group A was kept as a control and not treated. The group B was supplemented with papaya leaf and kalo jeera powder with feed and water. Weekly observations were recorded for live body weight gain up to 5th weeks and hematological tests were performed at 35th day’s age of broiler to search for hematological changes between control (A) and treatment (B) groups. The initial body weight of groups A and B on 1st were 41.00±0.56 gm and 41.50±0.35 gm, respectively and after 35th day of experiment final body weight were 1470±57.35 gm and 1720±58.56 gm, respectively and economics of production were analyzed and found that net profit per broiler was Tk. 8.91 and Tk. 20.69, respectively. The treatment group B was recorded statistically significant (at 1% level) increased (17.00%) for live body weight than that of control group A. The hematological parameters total erythrocyte count (TEC), erythrocyte sedimentation rate (ESR) and hemoglobin (Hb) estimation value of treatment group shows significant difference, while hemoglobin estimation does not show significant difference from control group. The results suggest that better growth performance could be achieved in broilers supplemented with papaya leaf and kalo jeera seeds.

The experimental trial was carried out to study the effect of multiple phase feeding on the growth performances and the economics of broiler production for a period of six weeks. Day-old chicks (n=160) were divided into two treatment groups, each containing 80 chicks with four replicates in each treatment. The birds of the control group (A) were fed prestarter, starter and finisher diets as per nutrient requirement of commercial broiler strain used in the experiment and the multiple phase feeding was followed in group-B by changing the nutrient densities (Energy, Crude protein, lysine and methionine) of diet per week. The different performance parameters were studied such as live body weight, gain in live body weight, feed conversion ratio and feed consumption at weekly interval. Mortality was recorded daily and the economics was calculated at the end of experiment. The results of experiment showed that the body weight and weight gain of broilers of group-B was significantly higher (p less than 0.05) than that of broilers of group-A during first, second, fifth and sixth week of age and also during overall duration of the experiment. Further, the feed intake of broilers of group-B was significantly higher (p less than 0.05) than that of group-A during second, fifth and sixth weeks of age and also during the overall feed intake of broilers. The Feed Conversion Ratio of broilers of group-B was significantly better (p less than 0.05) than that of group-A during fifth week and also during the overall performance. The multiple phase feeding has not put any adverse effect on percentage mortality of broilers. However, broilers fed with the multiple phase feeding showed higher net profit per bird and also per kg of body weight as compared to the broilers of control group (A).

The aim of the study was to find the responses of acid-base parameters and performance parameters of turkeys to a corn silage (CS) diet with different values of the dietary cation-anion difference (DCAD). The turkeys were fed as follows: group A (control) – standard diet (SD) (60%) plus CS (40%); group B – SD (60%), CS (40%) plus 240 g of CaCl2 per100 kg of diet; group C – SD (60%), CS (40%) plus 480 g of CaCl2 per 100 kg of diet; group D – SD (60%), CS (40%) plus 240 g of NaHCO3 per 100 kg of diet; group E – SD (60%), CS (40%) plus 480 g NaHCO3 per 100 kg of diet. The addition of the smaller amount of CaCl2 reduced DCAD, which ranged between 49.75 ± 6.29 mEq/kg DM and 93.56 ± 3.34 mEq/kg DM. An increased content of CaCl2 led to high, negative values of DCAD. NaHCO3 supplemented in both doses resulted in a significant elevation of DCAD. The addition of CS to the SD led to a lower body weight in comparison to that in the B, C, D and E groups. Forage acidification and alkalization improves body weight gain (BWG) at every stage of feeding. Compared to the control group, the anion gap was insignificantly lower in birds exposed to the acidic diet, and was comparable to the decrease in HCO3 –. Conversely, the addition of NaHCO3 to the diet led to a marked elevation in HCO3 – to 29.63 ± 0.4 mEq/L in group D and to 30.3 ± 0.69 mEq/l in group E. In conclusion, a change in DCAD during the feeding of forage containing CS exerts stimulatory effects on productive parameters of turkeys....

The present study was undertaken to investigate the antidiabetic effect of the Bitter melon and Garlic on Alloxan induced diabetes in experimental rabbits. At 2 to 3 months of age, rabbits were assigned into five groups (A, B, C, D and E) and each group was remained 4 rabbits. Group A was kept for control, Group B was treated with Alloxanintramuscullarly at a dose of 75mg /kg body weight, Group C was treated with bitter melon 250gm/kg body weight orally, Group D was treated with garlic 750mg/kg body weight orally, Group E treated with combined at previous dose. After acclimatization, diabetes was induced in four groups of rabbits (B, C, D and E) by administering Alloxan injection in a dose of 75mg/kg body weight (b.wt.) intramuscularlly. There was significant decreased in blood glucose level in all treated group C, D, E compared to the B group and lowest glucose was recorded in E group when treated with combined medicinal herbs and body weight was increased in all treated group C, D, E compared to the B group and highest was recorded in Dgroup while treated with those.% of PCV level and Hb gm/dl concentration was the highest in group E which was treated with both garlic and bitter melon compare to the A group. ESR was highest in group B treated with Alloxan and lowest in group E. The present study reveals that combined treatment increases body weight and decreases glucose level without affecting health of rabbits.Asian J. Med. Biol. Res. September 2016, 2(3): 402-408

Introduction: NSAIDs are known to cause salt and water retention leading to hypertension and renal impairment. Aloe vera gel has been used in medicinal preparations for decades. Limited data is available regarding effect of Aloe vera on renal function. There is a need to search this aspect of Aloe vera, to use it judiciously. Aims & Objectives: To estimate and compare the effects of Aloe vera and diclofenac on systolic blood pressure and renal functions of hypertensive rats. Place and duration of study: This study was conducted at Post Graduate Medical Institute Lahore, Sargodha Medical College, Sargodha and Department of Pharmacy, University of Sargodha for the period of three months. Material & Methods: Male Sprague Dawley rats (n=24) were divided into four groups; Group A (Normal control), Group B (Hypertensive control), Group C (Aloe vera treated) and Group D (Diclofenac treated). Hypertension was induced in groups B, C and D by 20% sucrose diet in 8 weeks. After induction of hypertension, distilled water, dried Aloe vera gel 400 mg/kg and diclofenac 12 mg/kg were given orally to group B, C and D respectively for 2 weeks as a single morning dose. Body weight and systolic blood pressure were measured weekly, while serum creatinine, creatinine clearance and urinary proteins were estimated and compared at 0, 8 and 10 weeks. Data was analyzed using SPSS 23 and p value of ?0.05 was considered significant. Results: Diclofenac decreased body weight of rats non-significantly and increased systolic blood pressure significantly (p< 0.03) whereas Aloe vera increased body weight significantly (p<0.012) and had no significant effect on systolic blood pressure. Diclofenac treated group showed deterioration of renal function as compared to Aloe vera treated group numerically. Conclusion: Aloe vera may be safer anti-inflammatory agent than diclofenac for treatment of chronic inflammatory conditions if the patient also has hypertension or renal disease.

Objective: To determine the anti-hyperglycemic effects of interleukin-1 inhibitor (diacerein) in alloxan induced diabetic albino wistar rats. This experimental study was performed at the Department of Animal Husbandry and Veterinary Sciences, Sindh Agriculture University, Tando Jam within 6 months from April 2016 to September 2016. Total of 160 adult Albino Wistar Rats having an average of 200 to 300 grams body weights were selected. Animals were categorized into 4 groups as; Group A (n=15): Control rats – receive 0.9% normal saline as placebo Experimental Groups Group B (n=15): Experimental Control (Diabetic rats) - Alloxan50 mg/kg body weight intraperitoneal. Group C (n=15): Diabetic rats + Diacerein (30 mg/kg/day) orally daily. Group D (n=15): Diabetic rats + Diacerein (50 mg/kg/day) orally daily. Animals were kept and treated as per the NIH Guideline for Use and Care of Laboratory Animals. Diabetes mellitus was induced via a single intraperitoneal injection of 50 milligram/kg alloxan monohydrated dissolved in aseptic 0.9% saline. After 72 hours, blood specimens were taken from the caudal vein of the rats and glucose level>200 mg/dL was taken as diabetes. Experimental rats were given diacerein approximately 30 and 50 mg orally for 6 weeks. At the completion of experiment the body weight was measured of each animal by electronic measuring balance and blood sample was taken from each animal of all groups to assess the blood glucose level and HbA1c level. Data were recorded via self-made proforma and analysis was done by using SPSS version 20. Results: Average body weight of Diabetic control (Group B) was 193.33±22.50 grams, which was lower in contrast to Diacerein treated group C 202.47±25.70 grams and significantly lower as compared to Diacerein treated group D as  212.6±23.43 grams. A significant increase in blood glucose levels 182.07±10.63 mg/dl was noted in the Diabetic control (Group B) compared to Diacerein treated group C (110.13± 8.54 mg/dl) and group D (85.87±8.41 mg/dl) (P=0.001). HbA1c was markedly raised in the Group B- diabetic controls, while diacerein treated diabetic rats (groups C and D) showed a significant decrease in HbA1c (P=0.001). Conclusion: It was concluded that Diacerein achieves the Euglycemic state by reducing the levels of blood glucose and glycated hemoglobin (HbA1c) in Alloxan-Induced diabetes mellitus in Wistar Albino Rats.

Essential oils are plant secondary metabolites possessing various pharmacological properties, primarily anti-oxidative, antimicrobial or immunomodulative, but they can exhibit toxic and allergic effects as well. The aim of this study was to compare the effects of Rosmarinus officinalis essential oil dietary administration in carrageenan paw oedema and trinitrobenzene sulfonic acid (TNBS) colitis. ICR mice received rosemary essential oil at three concentrations (1 250, 2 500 and 5 000 ppm) in the standard laboratory diet starting two weeks before the experiments. The inflammation of paws induced by carrageenan application was evaluated by measurement of paw swelling, paw weight and myeloperoxidase activity. In the TNBS model the mice were killed by cervical dislocation 3 days after colitis induction and the mortality, changes in the body weight of mice, colon weight : body weight ratio, macroscopical scores and myeloperoxidase activity were analysed. Furthermore, IL-1β and IL-6 cytokine levels in colonic tissue were quantified using ELISA assay. Dietary supplementation with 5 000 ppm of rosemary essential oil initially after 2 h increased but after 24 h suppressed the extent of paw oedema. The same dose in the TNBS model exhibited protective effects on colonic mucosa and significantly decreased macroscopic scores for colonic inflammation. On the other hand, in colon samples from mice fed the diet with 1 250 ppm of rosemary essential oil we detected decreased myeloperoxidase activity and significantly lower levels of IL-6 compared to TNBS control animals. Our results indicate that rosemary essential oil is able to influence several variables of murine experimental inflammatory models depending on the concentration used. We conclude that the anti-inflammatory effects of rosemary essential oil should be interpreted carefully due to its timeand dose-related effects.
