Diabetic nephropathy (DN) is a common complication and the leading cause of end-stage renal disease (ESRD) in diabetic patients. The occurrence of non-diabetic renal disease (NDRD) in diabetic patients has been increasingly recognized in recent years. Generally, renal injuries in DN are deemed difficult to reverse, whereas some NDRDs are often treatable and even remittable. Thus, the diagnosis of NDRD in patients with diabetes mellitus (DM) via a kidney biopsy would be significant for its prognosis and therapeutic strategy. According to recent studies, the most common NDRD is IgA nephropathy in type 2 diabetic patients, and some cases of minimal change disease and membranous glomerulonephritis have been reported in Korea. However, membranoproliferative glomerulonephritis (MPGN) is an uncommon condition in diabetic patients. To our knowledge, there has been no case yet of MPGN, except in a child with type 1 DM. We present an unusual case of a 27-year-old woman who had type 2 DM with MPGN, as confirmed via a kidney biopsy.

The purpose of this study is to evaluate the effectiveness in the lighting performance of mixed type light-shelf, by comparing and analyzing the internal light-shelf, external light-shelf, and mixed-type light-shelf. The performance of light-shelf was evaluated according to the angle of light-shelf at summer solstice, winter solstice, vernal equinox, and autumn equinox. The comparative analysis between the internal light-shelf, external light-shelf, and mixed-type light-shelf was carried out using the performance evaluation and analysis method. The result of performance evaluation is shown as follows. The mixed type light-shelf showed the highest lighting performance all at summer solstice, winter solstice, vernal equinox, and autumn equinox, followed by the external light-shelf and the internal light-shelf in the same order. The mixed type light-shelf was the most favorable for bringing daylight to indoors by adjusting the angle of light-shelf, and it also showed the highest lighting performance in terms of uniformity ratio of illumination which indicates the quality of light.

Purpose : The purpose of this study was to evaluate the effect of amount of cantilever in intra-crown according to implant fixture position on mechanical strength of internal conical joint type implant. Materials and Methods : Internal conical joint type implant fixture, abutment screw, abutment was connected and gold alloy prostheses were fabricated and cemented on abutment. For fatigue fracture test, the specimens were loaded to the 350 N, 2,000,000 cycle on 3, 4, 5, and 6 mm off-center of gold alloy prostheses. The fracture pattern of implant component was observed. Results : No fatigue fracture found on 3 and 4 mm group. But initial crack pattern found on 3 specimens of 4 mm group. Fatigue fracture found on all specimens of 5 mm group. But complete fracture was not observed. One specimen of 6 mm group fracture completely. Implant fixture fracture wax not observed. Conclusion : The mechanical failure of implant prostheses increased with the loading area farther from center of implant fixture. To reduce mechanical problem of internal joint type implant, surgical and prosthetic consideration is needed.

Whole-Body counters have been used to evaluate the internal contamination of gamma emitting radionuclides. Among the whole-body counters used in domestic nuclear facilities, Fastscan made by CANBERRA contains 2 NaI(Tl) detectors and is generally used to monitor the primary internal exposure. It has the advantage of achieving MDA even with short time measurements. Accuscan is a bed type, and has good energy resolution because it is composed of HPGe detector. Since the Accuscan with better energy resolution than Fastscan has better able to identify radionuclides, it is used to monitor secondary internal exposure. Some nuclear facilities have only Fastscan. We analyzed statistically whether Fastscan is enough to ensure accuracy and precision comparing with Accuscan. To do this, we prepared a CRM created by the Korea Research Institute of Standards and Science. We also obtained the data of 6 Fastscans and 5 Accuscans in domestic nuclear facilities. As a result of the study, although Fastscan compared with Accuscan is not as accurate as the Accuscan, the precision is statistically same. However, accuracy of Fastscan is in compliance with international standards except low energy range. In terms of accuracy and precision except radionuclides emitting low energy, it is possible to measure radioactivity inside workers even in nuclear facilities where only Fastscan is used.

Objectives: The purpose of this study is to assess the antidiabetic effect and safety of Galgunhwangryunhwanggum-tang for type 2 diabetes without complications by analyzing related research. Methods: For a systematic review and meta-analysis, we searched for the antidiabetic effect and safety of Galgunhwangryunhwanggum-tang for type 2 diabetes without complications in 10 databases up to September 2021. Only randomized controlled trials were chosen. Results: In the treatment effectiveness analysis and meta-analysis, Galgunhwangryunhwanggum-tang had significant improvement effects on fasting plasma glucose level, 2-hour postprandial glucose level, glycated hemoglobin, fasting insulin, and homeostasis model assessment for insulin resistance compared to the control group when treated in parallel with oral glycemic drugs. Conclusion: Galgunhwangryunhwanggum-tang is effective in improving blood sugar and insulin resistance in type 2 diabetes patients without complications and can especially be considered in parallel treatment with oral hypoglycemic drugs. A large-scale randomized controlled clinical trial is required to complement the limitations presented in this study in the future.

Objectives : Cordyceps Sinensis (CS) was tested for the effects of antioxidant enzymes and lipid peroxidation in the liver. Methods : We measured the changes in body weight, enzyme activity, lipid peroxide and the death rate in the hydrocortisone acetate-treated rats. Results : In vitro, CS didn't effect levels of lipid peroxide. the activities, and the ratio of type conversion of xanthine oxidase. In the hydrocortisone acetate-treated rats, lipid peroxide, the activities, the ratio of type conversion of xanthine oxidase, and the death rate all increased. But, glutathione peroxidase and superoxide dismutase decreased. In vitro, after CS was administered to hydrocortisone acetatetreated rats, the levels of lipid peroxide in the liver, and the death rate decreased. However, the activities, and the ratio of type conversion of xanthine oxidase decreased. The body weight, glutathione peroxidase, and superoxide dismutase in+creased. The effects of Sinensis Cordyceps Broth did better than the effects of Sinensis Cordyceps Mycelia. Conclusions : These results suggest that CS decrease the activities of free radical generating enzymes which form lipid peroxide and increase the activities of oxygen free radical scavenging enzymes.

Introduction: We describe the effects of Sosiho-tang decoction and insulin combination therapy, as well as the effect of integrated traditional Korean medicine therapy, using continuous glucose monitoring (CGM) in a diabetic patient complaining of a range of diabetic symptoms. Case report: A 24-year-old female presented with symptoms of diabetes, including weight loss, thirst, and polyuria, and was diagnosed with type 2 diabetes through blood tests, endocrine tests, and autoantibody tests. During hospitalization, the patient received insulin therapy and Sosiho-tang decoction concurrently, achieving normal blood glucose levels. After discharge, adhering to the Sosiho-tang decoction and CGM enabled the insulin dosage to be gradually reduced while maintaining normal blood glucose levels. Conclusion: Combination therapy with insulin and Sosiho-tang rapidly reduced hyperglycemia in the short term. CGM post-discharge allowed for observation of the patient's blood glucose levels. Ultimately, Sosiho-tang medication lowered blood glucose levels, reduced insulin requirements, and facilitated a reduction in the insulin dosage.

Improving the atomization characteristics by adopting the Air-Shrouded injector has been considered as one of the important methods for decreasing HC emissions in SI engines. Thus, in this study for the purpose of developing Air-Shrouded injector which has a finer spray, atomization characteristics of different types of commercial Air-Shrouded injectors were investigated through the spray imaging and the drop size measurements. As a result, it was found that the internal mixing type of Air-shrouded injector had a good atomization characteristics. But, a number of large droplets were found in the internal mixing type commercial injector, this phenomenon was improved by adopting the thread type nozzle passages.
