ABSTRACT

The renal artery exhibits wide spectrum of origin variation. The renal artery anatomy plays a considerable role in selecting donors. 3-D angiotomography is the best modality for vascular anatomic evaluation. The aim of the present study was first, to provide morphometric data concerning the renal arteries in people of Aseer region, K.S.A. and second, to establish relationships between those arteries. Methods: Data from a retrospective review were performed using 3-D MDCT angiography of 100 consecutive Saudi patients fulfilled all research criteria and had a readable CTA were selected (54 males and 46 females) with mean age 54.7±5.2 years. Results: The median level of the origin of right renal artery and left renal artery is at the level of the lower third of L1 and the disc between L1 and L2, respectively. The mean of the measured angle of the right renal and left renal arteries is 55º±7º and 85º±8º, respectively. There was no difference between the diameters of the main renal arteries. The renal artery diameter had a direct correlation with the angle of origin. The renal artery diameter in kidneys with extra renal artery was significantly lower than those without an extra renal artery. Renal arteries associated with extra renal artery showed greater length. The length of the segment between celiac trunk and the renal arteries was significantly correlated with the length of the abdominal aorta. Conclusion: Understand the position, calibre and angle of the renal arteries, were advantageous to make use of selective arteriography, arterial embolism therapy and plan stent grafts.

Mohamed A Eid, Mostafa S Ali

ABSTRACT

Background/Purpose: The aim of the study was to investigate the combined effect of electromagnetic field and therapeutic exercises on lean muscle mass in children with juvenile rheumatoid arthritis (JRA). Methods: Thirty children with polyarticular JRA were included in this study. Fifteen children represent study group and treated with electromagnetic field and therapeutic exercises and fifteen children represent control group and treated ith therapeutic exercises only. Lean muscle mass was determined before and after six months of treatment. Results: Pre-treatment results of both groups indicate that mean lean muscle mass was 23975.2± 8152.21 gm. (mean ± SD) in control group and 24016.26 ± 7864.39 gm.in study group. There was no significant difference between both groups which indicate they were homogenous (p = 0.98). But post-treatment results showed that mean lean muscle mass was 24143.26 ± 8416.94 gm. in control group while that of study group was 27488.8 ± 7543.39 gm. which was significantly higher than the control group (p = 0.26). Conclusion: We conclude that treatment with electromagnetic field together with therapeutic exercises are effective in increasing lean muscle mass in children with polyarticular JRA than therapeutic exercises alone.

ABSTRACT

Objective  To study the delay of denervated skeletal muscle atrophy after transplantation of mesenchymal progenitor cells (MPC) into the transected position and the muscle. Methods  MPC were taken from bones of hind limbs of GFP transgenic C57 mice for cultivation and identification. 48 C57 mice were divided into 4 groups evenly in random, group A (control group), group B (sham operated group), group C (MPC transplantation into transected position) and group D (MPC transplantation into muscle). 5μL MPC suspension were injected into the transected position of sciatic nerve and the gastrocnemius in group C and D, and 5μL Sodium Chloride was injected into the gastrocnemius in group B, while nothing was injected in group A. The locomotor ability of mice hind limbs was observed. The wet weight of gastrocnemius and the retain ratio of cross section area (CSA) of muscle fibers were measured and the ultrastructural structure was observed at 2 weeks and 4 weeks after the operation. The expressions of α-actin and myoglobulin (MHC) were detected with Western blot, and Myogenin and MyoD with RT-PCR. Results  The wet weight of gastrocnemius and the retain ratio of muscle fibers CSA of group C and D were obviously higher than those of group B at 2 weeks and 4 weeks after the operation (P < 0.01); The degeneration level of muscle cell nucleus, mitochondria and endocytoplasmic reticulum and the degree of muscle fibrosis of group C and D were obviously lower than those of group B at 4 weeks after the operation (P < 0.05), while the expression level of α-actin, MHC, Myogenin and MyoD was obviously higher than that of group B (P < 0.05). Conclusion  The transplantation of allogenic MPC in vivo is effective for the delay of denervated muscle atrophy.

ABSTRACT

The present study was carried in the famous Dal Lake Kashmir. The Dal Lake is a eutrophic water body and is contaminated due to various inflows directly as well as indirectly. Main source of pollution comes from Dal dwellers and surrounding areas. During present study the metal contamination has been assessed in the drinking water of Dal dwellers. The study showed that there is an increasing trend in the metal contamination in the lake, no doubt still out of danger.

ABSTRACT

Assessment of watershed management operation is one of the main subjects for future planning of practical projects and natural resources management. Flood Damage is one of the most important problems in countries same Iran, which is mostly, affected most parts of the country and caused hazards. Therefore, identification of the area with high potential risk of flood occurrence is the main purpose in order to the flood control and reducing its damages. Due to the lack of any tool for assessment of watershed processes in many cases, distributed hydrological models can be useful. The indicator watershed of Kushk-Abad Basin as the study area in Khorasan province of Iran divided to 6 sub-basins which was processed geometrically using GIS and HEC-HMS extension. With using HEC-HMS model and emission of individual repetition of the sub-basins, the homogenous flood hydrographs have gained in relation to the recorded precipitation calculated for different sub-basins. For this purpose, first by considering observed events, HEC-HMS model was optimized and calibrated. Then, for evaluating the effects of check dams on time of concentration, it was optimized and calibrated. Then, for evaluating the effects of check dams on time of concentration, it was calculated before and after of check dam’s construction by use of field observations and vegetation cover improvement was also estimated after the project. These parameters were imported to HEC-HMS to find out the effects of watershed practices and then flooding condition was simulated. For assessment purposes, peak discharche and flood volume were calculated for before and after construction conditions. Results showed that check dams as mechanical measures had low effect on time of concentration while biological practices lead to decease in curve number with an average value of 4.5. This result in decrease of peak flow and flood volume meanly 19% and 14%, respectively.

ABSTRACT

This study reports the effect of Anthocleista nobilis root extract on the haematological indices of poultry chicken challenged with Newcastle disease virus (NDV). Eighteen (18)-weeks-old chickens were used for this study. They were divided into 3 groups, A (chickens infected + treatment), B (chickens infected without treatment) and C (control). Groups A and B were challenged with Newcastle disease virus (NDV). Group A and C were given ethanolic root extract of A. nobilis orally at intervals of 6 h at 0.5mg per 100g of body weight for 28 days. All the chickens were given tetracycline antibiotic to eliminate bacterial infections. The average body weight and the temperature were monitored. The cytological examination of the chickens in group B showed that there was ulceration in the intestinal lining. All values for blood parameters were within the normal range for chickens before they were challenged with NDV. From our findings most of hematological indices of poultry chickens tend towards normal after treatment with the root extract of A. nobilis. This showed the ability of this plant extract to impact immunity in chickens suffering from Newcastle disease (ND). The packed cell volume (PCV), hemoglobin (Hb) and full blood count (TWBCC) were significantly different (P<0.05) between the Group A and Group B. The hematological indices of poultry chickens in group A were significantly (P<0.05) influenced by the treatments except for mean corpuscular haemoglobin concentration estimation (MCHC). It showed negligible differences (P>0.05) among the three groups, A (33.3% and 33.8% respectively), B (32.4%) and C (32.1%). They fell within the normal range of 30.0%-36.0%. This showed that the NDV did not affect that aspect. The study indicated a drop in the hematological indices of the infected and untreated chickens (Group B) while those of group A and C fell within normal range. The study showed that ethanolic root extract of Anthocleista nobilis was able to correct the haematological and physiological alteration associated with Newcastle disease among infected poultry chickens. The ability of group A poultry chickens to tend towards normal after treatment are physiological evidences of the antiviral effect of the root extract of A. nobilis on hematological indices of the poultry chickens studies. The study also showed that Anthocleista nobilis root extract was able to prevent further NDV infection of the poultry chickens. Thus, further studies on phyto-chemical and toxicological properties of Anthocleista nobilis as well as its antiviral property are advocated.
