Objective: To report and compare the hematological and serum biochemical profile of goat and sheep from Rahim Yar Khan district in Southern Punjab. Methods: One hundred and twenty blood samples (98 goat and 22 sheep) were collected and their blood glucose, hemoglobin and serum biochemical parameters, cholesterol, aspartate transaminase (AST), alanine aminotransferase (ALT) and lactate dehydrogenase (LDH) were determined by using spectrophotometer. Parameters were compared between goat and sheep. Results: It was observed that glucose (P=0.001), LDH (P=0.001) and ALT (P=0.001) concentrations differed significantly between sheep and goats. The studied parameters were compared between buck and goats and also between young goats (less than 12 months old) and adults (more than 12 months old). It was found that age and gender did not affect these hematological and serum biochemical parameters.Conclusions: It can be concluded that sheep have overall higher values than goats for studied hematological and serum biochemical parameters.

BACKGROUND: Pakistan has been hugely struck with massive bomb explosions (car and suicide bombs) resulting in multiple casualties in the past few years. The aim of this study is to present the patterns of skeletal and soft tissue injuries and to review the outcome of the victims who presented to our hospital. METHODS: This is a retrospective chart review from January 2008 to December 2012. The medical record numbers of patients were obtained from the hospital Health Information and Management Sciences (HIMS) as per the ICD-9 coding. RESULTS: During the study period, more than 100 suicide and implanted bomb blast attacks took place in the public proceedings, government offices, residential areas and other places of the city. Altogether 262 patients were enrolled in the study. The mean age of the patients was 31±14 years. The shrapnel inflicted wounds were present on to the upper limb in 24 patients and the lower limb in 50. CONCLUSION: Long bone fractures were the most common skeletal injuries. The fractures were complicated by penetrating fragments and nails which result in post operative infections and prolonged hospital stay.

BACKGROUND: Spinal anesthesia with bupivacaine, typically used for elective and emergency cesarean section, is associated with a significant incidence of hypotension resulting from sympathetic blockade. A variety of dosing regimens have been used to administer spinal anesthesia for cesarean section. The objective of this study was to compare the incidence of hypotension following two different fixed dosing regimens. METHODS: This was a randomized double-blind clinical trial with a two-sided design, 5% significance level and 80% power. After approval of the hospital ethics review committee, 60 patients were divided randomly into two groups. In one group, the local anesthetic dose was adjusted according to height and weight, and in the other, the dose was adjusted according to height only. RESULTS: Sixty women with a singleton pregnancy were included. Of the factors that could affect dose and blood pressure, including age, weight, height, and dose, only height differed between the groups. Mean heart rate was similar between the groups. Hypotension was significantly more frequent with dosage based on height alone than with two-factor dose calculation (56.7% vs. 26.7%; P = 0.018). CONCLUSIONS: Adjusting the dose of isobaric bupivacaine to a patient's height and weight provides adequate anesthesia for elective cesarean section and is associated with a decreased incidence and severity of maternal hypotension and less use of ephedrine.

AIM: To study the pattern of presentation and to highlight the common causes of primary benign orbital lesions.of Jinnah Postgraduate Medical Centre Karachi from July 1997 to August 2001 and then from September 2001 to date (Continued) at the Department of Ophthalmology of Chandka Medical College & Hospital Larkana. Only patients with primary benign orbital lesions were included in this study. All the patients were admitted in eye ward from the out patients department. The diagnosis of the disease was based on the presentation, clinical examination, investigations and histopathology of excised mass. A total of 68 patients were included in this study. The age range was from 2 months to 60 years. Out of 68, 27 (39.7%) patients were male and 41 (60.3%) were female. The left orbit was involved in 35 (51.5%) and right orbit was involved in 33 (48.5%).revealed that superficial capillary hemangiomas of the eye lid were the most common lesion 26 (38.2%) followed by deep orbital cavernous hemangiomas 5 (7.4%), lymphangiomas 5 (7.4%), orbital varices 4 (5.9%), gliomas 7 (10.3%), meningiomas 5 (7.4%), neurofibromas 5 (7.4%), neurofibromatosis 4 (5.9%), schwannomas 2 (2.9%), and pleomorphic adenoma (benign mixed cell tumor) of lacrimal gland 5 (7.4%) cases.treatment can prevent the patient from visual and life threatening complications.

AIM:To evaluate the site, size,histology,and recurrence of the tumor.METHODS: We prospectively evaluated 53 patients with histological diagnosis of retinoblastoma involving the eye, orbit, intra cranial cavity and other tissues, at Department of Ophthalmology, Chandka Medical College Hospital, Larkana. To assess the extent of the tumor investigations, including X-ray-orbits, ocular B-scan, CT-scan/MRI-Oorbits-brain, whole body bone scanning, X-ray chest PA view, ultrasound abdomen, lumbar punc-ture, complete blood cell count, blood chemistry as-sessment, including renal and hepatic function para-meters, were performed. The selection of mode of treatment like surgical procedures, local radiotherapy and systemic chemotherapy used depend on the site, size, recurrence and metastasis of the tumor. The patients with local and systemic metastases were referred to the oncologist at the Larkana Institute of the nuclear medicine and radiotherapy for local radiation and systemic chemotherapy. Follow up examinations were carried out at 1, 3 , 6 and 12 months after the operation, and then annually for a further 5 years or longer. The tumor's site, size, histological type, and recurrence were evaluated.RESULTS: Of these 53 patients the age range was from 8 months to 8 years. 25 (47%) were male and 28 (53%) were female. The laterality of the tumor was in left eye 25 (47%) cases, right eye 19 (36%) cases, and both eyes 9 (17%) cases. The presentation of the patient at 1st visit was strabismus 3 (6%) cases, pseudohypopyon 4 (8%) cases, orbital pseudo orbital inflammation 6 cases (11%), mass with metastases 7 (13%) cases, fungating mass 8 (15%) cases, leu-kocoria 12(23%) cases and orbital invasion 13(25%) cases. The surgical procedures performed were enucleation alone in 19 (36%) cases, enucleation with modified exentration followed by local radiotherapy and systemic chemotherapy in 19 (36%) cases and enucleation with total exentration followed by local radiotherapy and systemic chemotherapy in 15 (28%) cases. The histological types of the tumor were well- differentiated retinoblastoma with abundant rosettes in 25 (47%) cases and highly undifferentiated retino- blastoma 28 (53%) cases . After primary surgery, the recu-rrences and metastases of the tumors were noticed in 37 (70%) cases due to optic nerve involvement beyond the point of surgical transaction, orbital invasion and sy-stemic metastasis.CONCLUSION: Any child with red eye or white pupillary reflex should be suspected of having retinoblastoma, until proved otherwise, and should be promptly referred to an ophthalmologist, because early presentation of patient in the initial stage of the tumor will result in decreased risk of tumor extension, recurrence and mortality.

This study involves mathematical simulation model such as in vitro-in vivo correlation (IVIVC) development for various extended release formulations of nimesulide loaded hydroxypropylmethylcellulose (HPMC) microparticles (M1, M2 and M3 containing 1, 2, and 3 g HPMC, respectively and 1 g drug in each) having variable release characteristics. In vitro dissolution data of these formulations were correlated to their relevant in vivo absorption profiles followed by predictability worth analysis of these Level A IVIVC. Nimaran was used as control formulation to validate developed formulations and their respective models. The regression coefficients of IVIVC plots for M1, M2, M3 and Nimaran were 0.834 9, 0.831 2, 0.927 2 and 0.898 1, respectively. The internal prediction error for all formulations was within limits, i.e., < 10%. A good IVIVC was found for controlled release nimesulide loaded HPMC floating M3 microparticles. In other words, this mathematical simulation model is best fit for biowaiver studies which involves study parameters as those adopted for M3 because the value of its IVIVC regression coefficient is the closest to 1 as compared to M1 and M2.

Objective: To investigate the comparative effects of Diospyros blancoi (Ebenaceae) leaves (DBL), root bark (DBRB) and stem bark (DBSB) on free radicals and cancer. Methods: The polyphenol contents, antioxidant and free radical scavenging properties were determined using standard spectrophotometric methods. Cytotoxicity and anticancer activ-ities were performed on brine shrimp nauplii and Ehrlich ascite carcinoma cells, respectively. Results: Among the extracts, DBSB showed the highest total antioxidant capacity and reducing capacity on ferrous ion. Based on 1,1-diphenyl-2-picrylhydrazyl and hydroxyl radical scavenging activities, DBSB showed (95.760 ± 0.343)%and (67.460 ± 2.641)%scavenging with IC50 of (3.10 ± 0.17) and (50.00 ± 3.11) mg/mL, respectively. The IC50 values of standard butylated hydroxytoluene and catechin (CA) for 1,1-diphenyl-2-picrylhydrazyl and hydroxyl radicals were (8.50 ± 0.25) and (75.00 ± 0.14) mg/mL, respectively suggesting that DBSB had a significant (P < 0.05) radical scavenging ac-tivity than standards. In lipid peroxidation inhibition assay, the inhibitory activity of the extracts and the standard was in the following order: DBSB > DBRB > CA > DBL. Also, the phenolic [(139.91 ± 3.924) mg gallic acid equivalent/g] and flavonoid contents [(412.00 ± 16.70) mg catechin equivalent/g)] of DBSB were higher than that of other extracts. In addition, the DBSB showed the moderate cytotoxic and anticancer properties. Conclusions: Our results indicate that Diospyros blancoi stem bark had the significant highest antioxidant and free radical scavenging properties as well as moderate anticancer activity. Hence, we assume that the anticancer activity of this plant can be, at least in part, attributed to its content in phenolic compounds as well as its significant free radical scavenging properties.

Hollow-fiber liquid-phase microextraction (HF-LPME) and electromembrane extraction (EME) are miniaturized extraction techniques, and have been coupled with various analytical instruments for trace analysis of heavy metals, drugs and other organic compounds, in recent years. HF-LPME and EME provide high selectivity, efficient sample cleanup and enrichment, and reduce the consumption of organic sol-vents to a few micro-liters per sample. HF-LPME and EME are compatible with different analytical in-struments for chromatography, electrophoresis, atomic spectroscopy, mass spectrometry, and electrochemical detection. HF-LPME and EME have gained significant popularity during the recent years. This review focuses on hollow fiber based techniques (especially HF-LPME and EME) of heavy metals and pharmaceuticals (published 2017 to May 2019), and their combinations with atomic spectroscopy, UV-VIS spectrophotometry, high performance liquid chromatography, gas chromatography, capillary elec-trophoresis, and voltammetry.
