BACKGROUND/AIMS: Hypoalbuminemia occurs frequently in renal transplant recipients immediately after renal transplantation. We studied the regulation of hepatic albumin synthesis by cyclosporin A (CsA) in Huh7 cells. METHODS: Huh7 cells were incubated with various concentrations of CsA for 4, 8, 16, and 24 hours. Albumin was measured in Huh7 cell-conditioned medium by sandwich enzyme-linked immunosorbent assay and Western blot. Albumin mRNA expression was analyzed by Northern blotting in CsA-treated cells. RESULTS: CsA (10(-7)-10(-4) M) inhibited albumin synthesis in Huh7 cells in a dose- dependent manner. A Western blot analysis for albumin in the conditioned medium released from CsA-treated (10(-7)-10(-5) M) cells also showed significant inhibition of albumin synthesis in a dose-dependent manner. Vehicle (olive oil) did not affect albumin synthesis. In contrast, a Northern blot analysis revealed no inhibition of albumin mRNA expression by CsA at any time point from 1-24 hours, indicating that the inhibition of albumin synthesis occurred at the translational level. CONCLUSIONS: Our results suggest that inhibition of hepatic albumin synthesis by high dose CsA contributes to the hypoalbuminemia in renal transplant recipients.

OBJECTIVES: Retinal vein occlusion (RVO) is associated with an increased risk of future cardiovascular events. Statin therapy is a key cornerstone in prevention for patients at high cardiovascular risk. However, little is known about the role of statin therapy for patients with RVO. This study evaluated whether statin treatment in patients with RVO was associated with a lower risk of cardiovascular events. METHODS: A population-based, nested case-control study was conducted with a cohort of newly diagnosed RVO patients without prior cardiovascular disease between 2008 and 2020 using a nationwide health claims database in Korea. From this cohort of RVO patients, we identified cases of cardiovascular events (stroke or myocardial infarction) after RVO and matched controls based on sex, age, insurance type, antiplatelet use, and underlying comorbidities using 1:2 incidence density sampling. RESULTS: Using a cohort of 142,759 patients with newly diagnosed RVO, we selected 6,810 cases and 13,620 matched controls. A significantly lower risk of cardiovascular events (adjusted odds ratio, 0.604; 95% confidence interval, 0.557 to 0.655) was observed in RVO patients with statin treatment than in those without statin treatment. Statin treatment was associated with a reduced risk for both stroke and myocardial infarction after RVO. Longer statin treatment after RVO was associated with a lower risk for cardiovascular events. CONCLUSIONS Statin treatment was associated with a lower risk for future cardiovascular events in patients with newly diagnosed RVO. Further studies are warranted to clarify the potential cardiovascular preventive role of statins in patients with RVO.

Akt, heat shock protein (HSP72)72, and HSP90 induced by ischemic preconditioning protect cells from the ischemic injury. The purpose of this study was to examine the alterations of the level of phospho-Akt, HSP72, and HSP90 in the rat tibialis anterior and soleus muscles after cyclic episodes of ischemic preconditioning. Sprague-Dawley rats aged 35 weeks were divided into control and ischemic preconditioning (IP) groups. The IP group was divided into 3 subgroups based on cycles of IP. Left common iliac artery was occluded 3, 6, and 10 times for 5 minutes, followed by 5 minutes reperfusion. The experimental animals were sacrificed at 0, 3, 6, 24, and 72 hours after reperfusion, and left tibialis anterior and soleus muscles were removed. The expression of phospho-Akt, HSP72, and HSP90 were examined with immunohistochemical methods and Western blot analysis. The results were as follows; 1. In the 3 and 6 times of IP groups, the expression of phospho-Akt (p-Akt) was increased at 0 and 3 hours after reperfusion, compared with control group. The expression of p-Akt in the 10 times of IP group was lower than that in 3 and 6 times of IP groups. At 72 hours after reperfusion, the expression of p-Akt showed no difference among the IP groups. The expression of p-Akt was higher in Soleus than that in Tibialis anterior. 2. The expression of HSP72 in 3 times of IP group increased at 0 and 3 hours after reperfusion, compared with 6 and 10 times of IP groups. The expression of HSP72 in the 10 times of IP group was lower than that in 3 and 6 times of IP groups. At 72 hours after reperfusion, the expression of HSP72 showed no difference among the IP groups. The expression of HSP72 was higher in Soleus than that in Tibialis anterior. 3. In the 3 and 6 times of IP groups, the expression of HSP90 increased at 0 and 3 hours after reperfusion, compared with control group. The expression of HSP90 in the 10 times of IP group was lower than that in 3 and 6 times of IP groups. At 24 hours after reperfusion, the expression of HSP90 showed no difference with increasing episode of IP. The expression level of HSP90 was higher in Soleus than that in Tibialis anterior. These findings suggest that ischemic preconditioning increases the expression of p-Akt, HSP72 and HSP90 at early phase after reperfusion in the rat tibialis anterior and soleus muscles. However, increased cycles of ischemic preconditioning may not induce the expression of them.

Angiosarcoma is a rare and highly malignant vascular tumor of endothelial cell origin. Cutaneous angiosarcoma usually occurs on the scalp and face of the elderly person, frequently in the sixth and seventh decade. Unusually, we experienced a case of angiosarcoma of the scalp in a 12-year-old girl. The patient had a solitary, well-demarcated 0.7X0.7cm sized, non-tender, blue-violaceous to gray-black colored, crusted papule on the vertex for 2 months. She was treated by wide surgical excision only but no recurrence in the last eight years after excision.

Background: Light-based and laser therapy have emerged as alternative therapies for the treatment of acne. Blue and red light-emitting diode (LED) phototherapy and pulsed dye laser (PDL) therapy are recognized as effective modalities in the treatment of acne vulgaris. Objective: To compare the efficacy of LED phototherapy and PDL therapy in the treatment of acne. Methods: We randomly allocated a total of 11 patients to receive LED combination therapy or PDL monotherapy.Outcome assessments included the number of inflammatory and non-inflammatory lesions, investigator’s and subject’s assessment, MexameterTM and CorneometerTM measurements. Results: Five men and six women were enrolled in the study. After treatment, a greater improvement in the inflammatory and non-inflammatory lesions was recorded in the LED treatment group. Erythema score decreased more in the PDL treatment group than in the LED treatment group. Patient’s self-satisfaction was better in the LED treatment group than in the PDL treatment group. Conclusion This study suggests that both combination LED phototherapy and PDL monotherapy could be effective in the treatment of acne. Additional large-scale studies should be conducted to compare the efficacy of these two treatments.
