Clinical Study of Rhodanese Enzyme in Renal Failure Patients

Rafidain Journal of Science, Volume 28, Issue 4, Pages 1-7

The research involved clinical study of rhodanese enzyme and its relation with some biochemical parameters in renal failure.
The result demonstrated a significant increase in the activity of rhodanese and metallo-endopeptidase and in concentration of urea, and potassium while a significant decrease activity of sulfate oxidase, thiosulfate oxidase and arylesterase and in concentration of albumin and sodium in renal failure patients compared with control.
The results also demonstrated a significant decrease in the activity of rhodanese in male compared with female in each of patients and control groups.
Correlation coefficients between rhodanese and biochemical parameters of renal failure patients showed that activity of rhodanese has negative correlation with activity of sulfate oxidase, thiosulfate oxidase and concentration of albumin while appositive correlation with activity of metallo –endopeptidase and concentration of urea in renal failure patients.
These results provide evidence of a major role for rhodanese enzyme in renal failure, which led to consider it as a marker for renal failure and its relation with biochemical parameters in patients group.

Watfa K. Younis; Farouk A. Kasir

Rafidain Journal of Science, Volume 17, Issue 3, Pages 78-87

Optimum total efficiency and output power were derived for Nd:YAG laser with symmetrical resonator configuration, taking into account a new interaction factor called spatial interaction efficiency factor. Under the assumption of the same pumping power and the same resonator losses, the results interacted a lower output power and higher lasing threshold provided that the mirror reflectivity was optimized as compared with a laser system that did not take the spatial interaction efficiency factor into consideration.

Hanan H. Ahmad; Farha K. Omar

Rafidain Journal of Science, Volume 22, Issue 6, Pages 60-72

In the present research, a spectrophotometric method is suggested as an alternative to the gravimetric method used to find mishraq alum purity. The method is based on the complex formation between aluminium ion and either Chrome Azurol S (CAS) or Eriochrome cyanine R (ECR) to give colored products suitable for the determination of aluminium. The same reaction has been applied to the determination of fluoride in tablet, depending on the bleaching effect of fluoride on the formed aluminium colored complex. Statistical comparison of method has given satisfactory results

Rafidain Journal of Science, Volume 17, Issue 11, Pages 8-15

Twenty bacterial isolates were collected from human diarrheal samples and then identified. Seven out of twenty isolates were E. coli and three P. mirabilis . These isolates were checked for their resistance to six antibiotics and two heavy metals ( HgCl2 and Cdcl2). The bacterial isolates showed variation in their resistance to antibiotics and heavy metals.and only one E. coli but all P. mirabilis isolates showed high level of resistance. Transposition induction of genes in the two chosen bacterial isolates was carried out.. Our results suggested that in E. coli isolate, neomycin resistance gene was induced to jump and insert itself into chloramphenicol and tetracyclin resistance genes causing them to mutate .in percents reaching 80% and 8% respectively. On the other hand, the streptomycin resistance gene transposition appear to be specific for generating mutations in the heavy metals resistance genes at rates 48% and 100 % respectively. In addition, transposition induction of the above genes in the chosen P. mirbilis isolate seemed to cause mutations in ampicilin, chloramphenicol and tetracyclin resistance genes ranging between 2 and 4 % .

The study of natural radionuclide materials is important to assess the health hazards on human being and one of these materials is 40 K which is present in soil and different types of stones. This study is performed to assess the 40K concentration in mudstones in the north of Iraq by (flame photometry and γ-ray spectroscopy) and to compare between these two techniques in measuring its level. So the activity of potassium was measured by these methods, and their results were compared with the results of other studies. The results show that the concentration of 40K ranges from 284.3 Bq/kg to 2481.2 Bq/kg using γ-ray spectroscopy and 511.7 Bq/kg to 3623.6 Bq/kg using flame photometer technique and these results were comparable with the upper level of the world mean specific concentration of 40K and cause no health hazard. The results obtained by the two methods were also, compared using T-test and P-value and they show no statistical significant difference.

Rafidain Journal of Science, Volume 27, Issue 3, Pages 62-76

This research was concerned with the isolation and identification of Vibrio parahaemolyticus from seafood (shrimp) samples. (40) samples of freshly harvested shrimp from the local markets in Al-Basra city and twenty (20) samples of frozen shrimp (Turkey origin) were collected. Two enrichment methods were used for the enhancement of the growth and isolation of vibrio species, which include enrichment in non selective medium Alkaline peptone water (APW) for 8 hours and then in selective broth salt polymyxin broth (SPB) and then plated on two solid selective media, ThioSulphate Citrate Bile Sucrose agar (TCBS) and Arabinose Ammonium Sulphate Cholate agar (AASC) and morphological, cultural and biochemical tests were performed on the colonies grown on selective media, then we confirmed the identification by using the chromogenic medium ChromagarTM Vibrio for the first time locally. Finally tox R based polymerase chain reaction was used to cofirm the identification of V. parahaemolyticus. The results showed the isolation of Vibrio parahaemolyticus, Vibrio vulnificus, Vibrio alginolyticus, Vibrio mimicus in percentage 45%, 20%, 37.5%, 17.5% from fresh shrimp, 35%, 20%, 25%, 15% from the frozen shrimp respectively. The results also showed that there is an accordenance between biochemical tests and ChromagarTM Vibrio. The results of tox R based PCR revealed that 22l25 of V. parahaemolyticus contain the tox R gene which is species-specific gene.
