1.Differentiation of Candida Species by PCR-SSCP Fingerprinting Analysis
Microbiology 1992;0(06):-
Thirty strains of seven Candida species from CICC(China Center of Industrial Culture Collection)were studied. The strains were differentiated by ITS1 region PCR-SSCP fingerprinting analysis and ITS2 region PCR-SSCP fingerprinting analysis. Results showed that both ITS1 region and ITS2 region were able to differentiate the seven species of Candida clearly. Contrasting the maps and effects on the identification of Candida species of ITS1 region with that of ITS2 region, result indicated that on the identification of Candida species the application of ITS2 region was better than ITS1 region.

ObjectiveTo analyze the clinical features of tertiary hyperparathyroidism. MethodsThe data including symptoms, past history, bone and joint X-ray, bone mass density, bone SPECT, blood routine, serum calcium, phosphorus, alkaline phosphatase, parathyroid hormone ( PTH), as well as parathyroid ultrasonic or CT,parathyroid ECT, and parathyroid pathology were collected from seven patients with tertiary hyperparathyroidism.ResultsThe first symptom in 6 patients was bone ache, one of them was thirsty, and 1 patient had fracture. Four patients had past history of gallbladder stone or renal stone. Four subjects presented with osteoporosis and 2 of them had fractures. All 7 patients suffered from hypercalcaemia, along with high PTH level, 6 with hypophosphataemia and 6 with high alkaline phosphatase level. The enlarged parathyroid glands were detected in five patients by ultrasonic or CT. Tc99 scans of parathyroid gland revealed hyperfunctioning nodes in 3 subjects. Six patients were operated, and pathological results showed adenoma in parathyroid gland in 5 patients and adenocarcinoma in 1 patient. Serum calcium and PTH levels returned to normal in all the operated patients.ConclusionsPatients who present bone ache, osteoporosis, spontaneous fracture, past history of gallbladder stone or renal stone, high serum calcium, and PTH levels, should be aware of the probability of tertiary hyperparathyroidism. The confirmed diagnosis depends on pathological result.

Purpose To investigate the expression of estrogen receptor ( ER) and progesterone receptor ( PR) in endometrial tissue in patients with intrauterine adhesion ( IUA) and their clinical significance. Methods Two experimental methods, immunohistochemical MaxVision two step method and real-time fluorescencequantitative PCR ( qRT-PCR) , were used for detection of ER and PR in endome-trial tissue both in group IUA ( study group) and non IUA group ( control group) . Results MaxVision immunohistochemical method showed that ER protein expression in the study group (3. 52 ± 0. 71) was significantly higher than that (2. 75 ± 1. 00) in the control group (P=0. 01), ER mRNA expression by qRT-PCR was also significantly higher in the study group (1. 59 ± 0. 26) than that (1. 00 ± 0. 19) in the control group (P=0. 00). The immunohistochemical detection of showed that PR protein expression in the study group (3.26 ±0.70) had no significant different from that (3.58 ±0.28) in the control group (P=0.12), qRT-PCR also showed that ER mRNA in the study group (1.15 ±0.21) had no significantly different from that (1.00 ±0.31) in the control group (P=0. 21 ) . Immunohistochemical expression of ER and PR proteins showed a significant difference between the endometrial glands and en-dometrial stroma (χ2 =5. 797, P=0. 016,χ2 =4. 857, P=0. 027). Conclusion The expression of ER in endometrial tissue in the study group is higher than that in the control group, but the expression of PR has no different between the two groups, ER and PR pro-teins expression are higher in endometrial glands than that in endometrial stroma. These provide a theoretical reference for clinical use of estrogen and progesterone to IUA patients.
