Henoch-$Sch{\ddot{o}}nlein$ purpura (HSP) is a systemic vasculitis characterized by purpura, arthritis, abdominal pain, and nephritis. Gastrointestinal involvement can manifest as pain, intussusception, intestinal bleeding, and intestinal perforation. We report a case of fulminant HSP at an age of eight in 1994, with multiple complications of intra-thoracic bleeding, massive intestinal perforation, nephritis, and various skin rashes. The brisk bleeding findings of intestinal on Technetium-99m-labeled red blood cell scan ($^{99m}Tc$ RBC scan) were well matched to those of the emergency laparotomy and the resected intestine. The patient's abdominal conditions improved gradually but nodular skin eruptions developed newly apart from improving preexisting lower limb rashes and the urine findings continued abnormal, so skin and kidney biopsy were done for the diagnosis. After cyclosporine therapy, skin eruptions and urine findings returned to normal gradually. On a follow-up after 25 years in 2019, the patient is 33-year-old, healthy without any abnormality on blood chemistries and urine examination.

There are a considerable number of reports suggesting a common pathogenesis of IgA nephritis(IgANn) Henoch-$Sch{\ddot{o}}nlein$ Purpura(HSP). In previous reports, a patient develops IgAN after kidney transplantation for HSP nephritis, one of Identical twin boys, developed IgAN and the other HSP, and a boy with IgAN later developed HSP. We report two cases, one with IgAN who later developed HSP and the other with HSP who later developed IgAN, suggesting that IgAN and HSP have a common pathogenesis. (J. Korean Soc Pediatr Nephrol 5 : 59- 63, 2001)

Cyclosporine is an immunosuppressant usually used to prevent renal transplantation rejection. Nephrotoxicity and hypertension are considered as the most frequent side effects of cyclosporine treatment. The neurotoxic effects of cyclosporine such as agitation, anxiety, delirium, depression and psychosis have recently been found. Methylprednisolone may increase as well plasma concentration of cyclosporine, which leads to side effects. Here we report a $Henoch-Sch\"{o}nlein$ nephritis patient treated with cyclosporine and methylprednisolone who has experienced psychosis including visual and auditory hallucination and convulsion.

This experiment was executed to control effectively endemic disease of swine farms in Incheon metropolitan city. Mainly using PigMon program which had been developed by the College of Veterinary Medicine in the University of Minnesota(USA), we examined lesions of gastric ulcer and interstitial nephritis additionally. 446 heads of pigs shipped from 5 farms in Incheon to a slaughterhouse from June in 2003 to May in 2004 were examined. Infection rates by farms were obtained as follows; 1. Pneumonia was varied from 34.6% to 74.1% and pneumonic score was 1.47∼7.06. As for atrophic rhinitis, four farms were 100% and one farm was 89.5% and rhinitis score was 1.3∼3.2. 2. The infection rate of pericarditis and peritonitis was 1.0∼3.9% and liver white spots, papular dermatitis were observed in pigs of 9.8∼29.7%, 16.7∼51.4% respectively. 3. The outbreak rates of interstitial nephritis, lesions of ileal thickening and gastric ulcer were 15.4∼24.1%, 7.7∼13.5%, and 62.7%∼86.2% respectively.

Objectives : The purpose of this study is evaluating the effect of Hoelen Herbal-acupuncture (HO-HA) at $KI_{10}$(Umgok) on Lipopolysaccharide(LPS) induced nephritis in rats. Methods : The experimental rats were assigned to four groups; normal, LPS, saline, HO-HA groups. LPS(2 mg/kg) was administered to the rats in LPS, saline and HO-HA groups to induce acute inflammatory kidney damage. Saline injection and HO-HA were administered at $KI_{10}$ three times a week. Blood samples were taken from the rats for analysis of white blood cell(WBC), neutrophil, blood urea nitrogen(BUN), creatinine TNF-${\alpha}$, CINC-1. Urine samples were taken from the rats for analysis of urinal volume, creatinine and total protein. The kidney samples were taken from the rats for analysis of renal myeloperoxIdase(MPO). Results : HO-HA suppressed the increases of WBC and neutrophils in blood, BUN, creatinine, TNF-${\alpha}$ and CINC-1 in serum, and MPO in kidney of LPS-stimulated rats. In addition, HO-HA inhibited the decrease of urinary volume in LPS-stimulated rats. Conclusions : HO-HA has therapeutic effects on LPS-induced inflammatory kidney damage in rats. Further studies may be needed for clinical use of HO-HA.

Background: Deposition of immune complexes drives podocyte injury acting in the initial phase of lupus nephritis (LN), a process mediated by B cell involvement. Accordingly, targeting B cell subsets represents a potential therapeutic approach for LN. Ginsenoside compound K (CK), a bioavailable component of ginseng, possesses nephritis benefits in lupus-prone mice; however, the underlying mechanisms involving B cell subpopulations remain elusive. Methods: Female MRL/lpr mice were administered CK (40 mg/kg) intragastrically for 10 weeks, followed by measurements of anti-dsDNA antibodies, inflammatory chemokines, and metabolite profiles on renal samples. Podocyte function and ultrastructure were detected. Publicly available single-cell RNA sequencing data and flow cytometry analysis were employed to investigate B cell subpopulations. Metabolomics analysis was adopted. SIRT1 and AMPK expression were analyzed by immunoblotting and immunofluorescence assays. Results: CK reduced proteinuria and protected podocyte ultrastructure in MRL/lpr mice by suppressing circulating anti-dsDNA antibodies and mitigating systemic inflammation. It activated B cell-specific SIRT1 and AMPK with Rhamnose accumulation, hindering the conversion of renal B cells into plasma cells. This cascade facilitated the resolution of local renal inflammation. CK facilitated the clearance of deposited immune complexes, thus reinstating podocyte morphology and mobility by normalizing the expression of nephrin and SYNPO. Conclusions: Our study reveals the synergistic interplay between SIRT1 and AMPK, orchestrating the restoration of renal B cell subsets. This process effectively mitigates immune complex deposition and preserves podocyte function. Accordingly, CK emerges as a promising therapeutic agent, potentially alleviating the hyperactivity of renal B cell subsets during LN.

Artemisinin, a new antimalarial to treat patients infected with strains of Plasmodium jalciparum, derived from the plant Artemisia annua Linn, has immunopharmacologic actions such as enhence the PHA -induced lymphocyte transformation rate, increased the weight of spleen but reduced the weight of thymus, reduced phagocytic function of peritoneal macrophage, remarkably reduced the level of serum IgG and hemolysin fonning capacity (sentitized with SRBC), inhibited the activity of Ts cells of donor mice by supraoptimal immunuization(SOI), but enhenced activity of Ts cells of recipient mice by SOI. These results suggested that Ts cells may be the target cells of artemisinin. To the serum complement C3 level of plasmodium berghei-infeted mice, artemisinin (i. m,) could remarkly increase it. The artemisinin also obviously reduced the prostaglandin E(PGE) in the mouse hind paw swelling induced by carrageenin. Numerous studies have demonstrated that pharmacologic doses of PGE attenuate the development of immunocomplex nephritis. Some autologous immune mechanisms may be invoolved In the pathogensis of some types of glomurulonephritis. Glomerular abnormalities can be induced in animals by variety of immunological manipulations. The resulting disorder has many clinical and pathogical similarities to the disease in human. Our purpose was therefore to test the ability of the artemisinin to lessen the severity of rabbit IgG accelerated nephrotoxic serum glomerulonephritis in mice model. Mice which had treated with rabbit IgG and NTS, administrated with saline, showed Significant inceases of urinary protein, cholesterol level, and decrease of serum albumin in NS group. On the contrary, By i.g. adminstration of artemisinin at dose of 12.5, 25 and 50 mg/kg for 14 days after NTS injection, shown that artemisinin inhibited the nephritic changes in some parameters by means of urinary protein(p<0.05, p<0.01) and serum choleterol(p<0.05, p<0.01) and albumin (p<0.05, p<0.01), blood urea nitrogen (p<0.05, p<0.01), serum albumin(p<0.05, p<0.01); Cyclophosphamide(i.p. 10mg/kg for 14d) had almost same effect as the artemisinin had. Morphological studies shown that The picture of kidney from the mouse with NTS-nephritis accerated with rabbit IgG, treated with i.g. saline as the control, the mesangiocapillary were enlarged and proliferated; There were inflammatory cells infiltrating around the glomeruli; The ethelial cell were proliferated in the wall of Bowman's capsule. Histopatholological picture of kidney from the NTS-nephritis accerated with rabbit IgG mouse treated with i.p. 10mg/kg cyclophosphamide as the positive control. No siginicant histopathological evidence were found. Treaded with i.p. 12.5mg/kg artemisinine, the picture shown that mesangiocapillary were lightly proliferated; There were inflammatory cells infiltrating around the glomeruli; Treaded with i.p. 25mg/kg artemisinine, The picture shown that the mesangiocapillary were lightly proliferated; Treaded with i.p. 50mg/kg artemisinine, The picture shown that both the mesangiocapillary proliferated and the inflammatory cells infiltrating around the glomeruli are less than treated with saline, 12.5 and 25 mg/kg artemisinine. On the basis of these studies we conclude that the artemisinin can relieve pathological change caused by NTS-nephritis aacerated with rabbit IgG.
