Plants have provided sources to find novel compounds. These plants are being used as therapeutic purposes since the birth of mankind. The traditional healers normally utilize medicinal plants as crude drugs while scientists using the folk claim as guides to explore medicinal plants. Moringa oleifera is a famous edible plant having therapeutic and nutritive values. The present study was designed to cumulate the research data regarding to what extent, phytochemical, nutritional and glycemic control studies has been explored using its different extracts. The articles indicated that the powder, aqueous, methanol and ethanol extracts of Moringa oleifera (leaves, pods, seeds, stem and root bark) have significant therapeutic herbal potential to treat diabetes mellitus. Collectively, the mechanism behind is intestinal glucose inhibition, insulin release as well as decrease in insulin resistance probably regeneration of b-cells of pancreas, increase in glutathione and reduction in malondialdehyde. Conclusively, this article give descriptive information about antidiabetic effect, claimed marker compounds and proposed antihyperglycemic mechanism of a single plant. It can be suggested a potential herbal source to treat diabetes mellitus as being widely accepted by major population as nutrition and therapeutic agent.

Although nasopharyngeal carcinoma (NPC) is common in this part of the world, the incidence among children is still very low
worldwide. The diagnosis is sometimes delayed because of the late reporting of the symptom by the patient or parents, or difficulty
in reaching the final diagnosis due to its hidden anatomical location. The challenges include the difficult endoscopy in children,
inability to differentiate an adenoid from the tumour on radiograph and often the inconclusive fine needle aspiration findings. If the
tumour mass at Fossa of Rosenmuller can be clearly appreciated and biopsied with undoubtedly proven histology of NPC, the
diagnosis can be straight forward and treatment can be commenced as early as possible. We report a 10-year-old child presented
with bilateral neck cervical lymphadenopathy and epistaxis with fine needle aspiration cytology (FNAC) of the neck mass reported
as lymphoma. Further work-up confirmed he was suffering from NPC.

The effect of loud noise to the army personnel is often identifi ed when hearing loss had already
developed. Acoustic trauma during shooting training can also lead to acute changes in the ear which is
shown on otoscopic examination. This study was undertaken to determine the effectiveness of hearing
protective device (earplug) on the prevalence of external ear changes amongst military personnel
during shooting. This is a prospective cross sectional study that was conducted among 76 military
personnel, who were divided into two groups: those with and without earplugs during shooting. Each
participant underwent 3 otoscopic examinations: (a) pre-shooting, (b) immediate post-shooting (within
48 hours) and (c) 2 weeks after shooting. A total of 78 army personnel who were scheduled to undergo
shooting training were otoscopically examined. Eighty three percent of them did not wear earplugs
before. The percentage of infl ammation of external auditory canal and tympanic membrane dullness
increased tremendously among subjects from non–earplug group less than 48 hours post-shooting.
Assessment after 2 weeks showed improvement in around 30% of the subjects. Loud noise has become
an occupational hazard not only to the inner ear but it also predisposes the external and middle ear
structures to some form of injury. Although improvement is seen after some period, a protective
device such as an earplug should be recommended and the usage should be reinforced among the
army personnel involved in shooting.

Annals of Coloproctology 2022;38(4):307-313
Purpose:
This study was aimed to assess the feasibility of laparoscopic rectal surgery, comparing quality of surgical specimen, morbidity, and mortality.
Methods:
Prospectively acquired data from consecutive patients undergoing laparoscopic surgery for rectal cancer, at 2 minimally invasive colorectal units, operated by the same team was included. Locally advanced rectal tumors were identified as T3B or T4 with preoperative magnetic resonance imaging scans. All the patients were operated on by the same team. The 1:1 propensity score matching was performed to create a perfect match in terms of tumor height.
Results:
Total of 418 laparoscopic resections were performed, out of which 109 patients had locally advanced rectal cancer (LARC) and were propensity score matched with non-LARC (NLARC) patients. Median operation time was higher for the LARC group (270 minutes vs. 250 minutes, P=0.011). However, conversion to open surgery was done in 5 vs. 2 patients (P=0.445), reoperation in 8 vs. 7 (P=0.789), clinical anastomotic leak was found in 3 vs. 2 (P=0.670), and 30-day mortality rates was 2 vs. 1 (P>0.999) between LARC and NLARC, respectively. Readmission rate was higher in the NLARC group (33 patients vs. 19 patients, P=0.026), due to stoma-related issues. There was no statistically significant difference in the R0 resection between the 2 groups (99 patients in LARC vs. 104 patients in NLARC, P=0.284).
Conclusion
This study demonstrates that standardized approach to laparoscopy is safe and feasible in LARC. Comparable postoperative short-term clinical and pathological outcomes were seen between LARC and NLARC groups.

Infectious bursal disease (IBD) is an acute and highly contagious disease of young chickens caused by Birnavirus. Mortality of infected birds can be best prevented if injected with antibodies. The present study was an attempt to raise specific hyper-immune polyclonal antibodies against IBD virus in Pakistan. Commercial layers divided into four groups were injected with IBD vaccine subcutaneously according to four different treatment regimens. Eggs were collected daily and antibodies were purified from yolk with dextran sulphate. Titers of antibodies in serum and yolk were evaluated with enzyme linked immunosorbant assay and agar gel precipitation test. Antibody titers were significantly higher in yolk than serum. Eggs collected at 28 days post-vaccination had maximum antibody titers. Of treatment regimens, T3 was found to be most effective for hyperimmunization. Lyophilized antibodies stored at 4oC did not lose their activity till the end of experiment. IBD virus infected birds were injected with purified antibodies which induced 92% recovery as compared to control birds. The study implicates that the purified antibodies may be useful as a therapeutic agent to cure IBD infected birds.

BACKGROUNDHepatitis C virus (HCV) constitutes a major public health issue around the world, especially in developing countries like Pakistan. In this study, we assessed outcome of interferon (INF) treatment in chronic hepatitis C patients categorized by gender, age, and viral load.
METHODSIn this study, 750 HCV positive patients with genotype 3 were selected, out of which 616 completed the entire treatment. Their personal history, pre-treatment HCV RNA and serum alanine transaminase (ALT) was quantified. Patients were treated with combination therapy of INF-α 2b three million units (thrice a week) plus ribavirin (1000 - 1200 mg per day) for 24 weeks. After 24 weeks their HCV RNA and serum ALT level was quantified.
RESULTSOut of the 616 patients, 391 (63.5%) responded to therapeutic regimen (INF-α 2b plus ribavirin). Among the responders, 27.1% were men and 36.4% were women. Best treatment response was observed in patients having low viral load < 8 × 10(5) IU/ml and age ≤ 40 years than patients having low viral load and age > 40 years (73.2% vs. 60.3%, P = 0.05).
CONCLUSIONSBetter response to IFN-α 2b plus ribavirin was observed in patients with lower viral RNA and younger age. It suggests that all patients considered for treatment should have quantification of serum HCV RNA level. The result can be used to counsel patients on the likelihood of response and may influence the patient's decision on treatment.

Objective: To investigate the pharmacological potential of Argemone mexicana in treating constipation and emesis by using in vitro and in vivo models.Methods: The spasmogenic and spasmolytic effects were evaluated on isolated rabbit jejunum fragments loaded in a tissue organ bath. The response was recorded with an isotonic transducer attached with Power Lab Data Acquisition System. The laxative and antiemetic activities were assessed in BALB-c mice and poultry chicks challenged with carbamylcholine and copper sulphate stimulated emesis, respectively. Results: The total phenolic and total flavonoids contents of the extract were (267.75 ± 5.77) mg GAE/g and (73.86 ± 6.01) mg QE/g, respectively. Argemone mexicana extract exerted spasmogenic effect on isolated rabbit jejunum segments with an EC50 value of 0.016 mg/mL, which was blocked by atropine (0.3 μM). Argemone mexicana extract exerted spasmolytic effect in atropine treated jejunum fragments with an EC50 value of 2.185 mg/mL. Furthermore, Argemone mexicana extract relaxed potassium (80 mM)-induced contractions (EC50: 9.07 mg/mL), similar to a standard drug verapamil. The calcium channel blocker activity was confirmed by a rightward shift of concentration-response curve of calcium in the presence of Argemone mexicana extract (1-5 mg/mL) and verapamil (0.1-1 μM). In addition, the extract increased the distance travelled by a charcoal in the gastrointestinal tract and exhibited antiemetic effect on copper sulphate induced emesis in chicks. Conclusions: Argemone mexicana shows cholinergic agonist and calcium channel blocker activities, as well as antiemetic effect. It may be used as a potential agent for treating gastrointestinal disorders.

OBJECTIVE: The aim of this study was to assess the analgesic effect of a single application of low-level laser therapy (LLLT) on spontaneous pain and pain on chewing after placement of initial archwires. METHODS: Forty-two patients (26 women, 16 men) were randomly recruited for this split-mouth randomized clinical trial. Each patient received super-elastic nickel-titanium (NiTi) initial archwires (0.012, 0.014, 0.016, and 0.018-inch [in]) in the maxilla for leveling and alignment for an interval of 4 weeks between archwires. One side of the mouth was randomly designated as experimental, while the other side served as placebo. After insertion of each archwire, the experimental side was irradiated with a diode laser for 3 seconds each on 5 points facially and palatally per tooth, from the central incisor to first molar. On the placebo side, the laser device was held the same way but without laser application. A numerical rating scale was used to assess the intensity of spontaneous and masticatory pain for the following 7 days. The Mann-Whitney U test was used to compare pain scores between sides. RESULTS: Patients in the LLLT group exhibited significantly lower mean scores for spontaneous pain after insertion of the initial two archwires (0.012-in and 0.014-in NiTi; p < 0.05), while there was no significant difference for 0.016-in and 0.018-in wires between the LLLT and placebo groups. LLLT significantly reduced chewing pain scores (p < 0.05) for all archwires. CONCLUSIONS: A single dose of LLLT considerably lessened postoperative pain accompanying the placement of super-elastic NiTi wires for initial alignment and leveling.
