Background: Cisplatin is still used as a first-line medication for solid tumors. Nephrotoxicity is a serious side effect that can decrease renal function and restrict applicable doses. This research aimed to obtain the profile of cisplatin-induced nephrotoxicity and its associated factors in adult cancer patients at Dharmais National Cancer Hospital (DNCH). Materials and Methods: The design was cross-sectional with data obtained from patient medical records. We retrospectively reviewed adult cancer patients treated with cisplatin ${\geq}60mg/m^2$ for at least four consecutive chemotherapy cycles from August 2011 to November 2013. The nephrotoxicity criterion was renal function decline characterized by creatinine clearance <60 ml/min using the Cockroft-Gault (CG) equation. Results: Eighty-eight subjects received at least four chemotherapy cycles of cisplatin. The prevalence of cisplatin nephrotoxicity was 34.1%. Symptoms could be observed after the first cycle of chemotherapy, and the degree of renal impairment was higher with increased numbers of cycles (r=-0.946, $r^2=89.5%$). Factors that affected the decline of renal function were patient age (p=0.008, OR=3.433, 95%CI= 1.363-8.645) and hypertension (p=0.026, OR=2.931, 95%CI=1.120-7.670). Conclusions: Cisplatin nephrotoxicity occurred in more than one-third of patients after the fourth cycle of chemotherapy and worsened after each cycle despite preventive strategies such as hydration. The decline of renal function induced by cisplatin ${\geq}60mg/m^2$ was affected by age and hypertension.

CW-270031 is a novel synthesized carbapenem antibiotic with a broad antimicrobial activity. Carbapenem antibiotics are well known for their nephrotoxicity. In this study, we evaluated the nephrotoxicity potential of this compound in rabbits, which are known for being more sensitive than other animals to renal insult. CW-270031 was administered to NZW male rabbits via an ear vein (200 mg/kg, single injection). Blood samples were collected on 2, 3, and 4 days after treatment. Urea nitrogen and creatinine in plasma were quantified. Four days after the treatment, all animals were autopsied and histopathological examinations were performed on their kidneys, revealing that cephaloridine and imipenem were highly nephrotoxic, and cefazolin had mild renal toxicity, whereas CW-270031 as well as meropenem and tienam had no toxicity to the kidney. The present findings suggest that CW-270031 is a potential carbapenem antibiotic with no nephrotoxicity.

The present study was designed to assess the protective effect of a selective thromboxane $A_2$ receptor antagonist, KT2-962 (KT2) and possible mechanisms of adriamycin(AD)-induced nephrotoxicity in rats. The male Wistar rats were given either of AD (7.5 mg/kg, i.v.) alone in the AD-group (n=5) or in KT2+AD- group (n=5) which is a combination of AD and KT2 (30 mg/kg/day, i.p.) for 10 days from 3 days before and 7 days after AD injection. The body weight, 24-hours urine volume, urine protein and urinary N-acetyl-$\beta$-D-glu-cosaminidase (NAG) activity were measured with an interval of 2 days during 1 week. BUN, serum creatinine and creatinine clearance were measured on the 7th day. KT2 has significantly suppressed AD-induced change of body weight, 24-hours urine volume, urine protein and urinary NAG activity in the KT2+AD-group. The change of BUN, serum creatinine and creatinine clearance were significantly inhibited in the B7T2+AD-group. Based on these results, it is concluded that KT2 prevents AD-induced nephrotoxicity and suggests that endogenous thromboxane A2 may play an important role in AD-induced nephrotoxicity in rats.

Diethanolamine Dithiocarbamate containing OH groups which gave water-soluble [Pt(dtc)$_{2}$] (diethanolamine dithiocarbamate) were synthesized from the reaction of CS$_{2}$ with diethanolamine. The complex has been characterized by elemental analysis, electrical conductivity, and spectroscopic results. Diethanolamine dithiocarbamate is effective as rescue and inhibition of cis-[$Pt(NH_{3})_{2}Cl_{2}$] nephrotoxicity in rats. It is suggested that diethanolamine dithiocarbamare removes platinum(II) complex coordinated to -SH groups of protein of kidney tubule cells.

Certain chlorinated propanols occur as contaminants in hydrolysed vegetable proteins. Processing of defatted vegetable proteins by traditional hydrochloric acid hydrolysis leads to the formation of 3-MCPD. The objective of this study was to determine the nephrotoxicity of 3-MCPD.(omitted)

Acetaminophen (APAP) and gentamicin are widely used for many patients, but little in-formation is available regarding the combined effects of APAP and gentamicin. This study was aimed to investigate the potent nephrotoxicity following combined-treatment with APAP and gentamicin. Serum biochemical parameters and histopathological changes in the kidney were observed in female SD rats after continuous daily treatment with either 600 mg/kg/day APAP, and/or 300 mg/kg/day gentamicin for 3 days, and compared with saline sham-treated control animals. APAP and gentamicin combination-treated rats exhibited inconsistent increasing tendency in blood urea nitrogen (BUN) by 96 hours after the last treatment, compared to control or the animals treated with each drug. The relative kidney weights were also increased. Histopathological findings of kidneys revealed that necrosis of proximal convoluted tubules were higher in rats treated with APAP and gentamicin combination than the rats treated with each drug alone. These results suggest that combination use of both drugs have more severe nephrotoxicity than treating each drug alone.

The treatment with gentamicin in the presence of pretreatment with bismuth nitrate significantly reduced blood urea nitrogen compared with given gentamicin alone. But the amelioration of gentamicin-induced nephrotoxicity by bismuth nitrate was abolished by pretreatment with indomethacin that is cyclooxygenase inhibitor, which significantly decreased renal glutathione S-transferase activity and thiobarbituric acid reactive substance compared with mice of given gentamicin and bismuth nitrate. On the other hand, treatment with bismuth nitrate significantly increased prostaglandin $E_2$ production in rat kidney slice. These results suggest that bismuth nitrate might ameliorate the nephrotoxicity of gentamicin via prostaglandin $E_2$ production.

This study is investigated the effect of Rubus coreanus MIQ. against nephrotoxicity induced by cisplatin in rat. We examined the potency of the extract of R. coreanus fruits by the activity-guided fractionation. The EtOAc- and BuOH fraction, niga-ichigoside F$_1$and 23-hydroxytormentic acid showed significant protective effects as lipid peroxidation in renal tissue and was was not affect the activity of xanthine oxidase and aldehyde oxidase by cisplatin-induced nephrotoxicity. The concentration of glutathione in renal tissue was decreased by cisplatin-induced nephrotoxicity, but was improved by pretreatment of R. coreanus compounds especially in butanol, ethylacetate fraction and 23-hydroxytormentic acid.

Cisplatinum is often effective in cancer treatment, but potent nephrotoxicity limits its clinical use. We have, therefore, developed new anticancer drugs that contain platinum. We have synthesized six new platinum compounds based on Figure 1. Drugs were initially administrated at 5${\times}$10$\^$-4/M with 48 hours exposure in monolayer cultures of primary rabbit proximal tubular cells and human renal cortical cells with the M.T.T. endpoint to measure toxicity. Drug concentrations of 10$\^$-3/M, 10$\^$-4/M, and 10$\^$-5/M with 72 hours exposure were used for human renal cortical tissues in 7 weeks histoculture with toxicity measured by the glucose-consumption endpoint. From these studies, we determined that the new platinum drugs have lower nephrotoxicity than cisplatinum. Drugs D, E, and H. have lower nephrotoxicity than the other new drugs. We are currently measuring the anticancer efficacy of drugs D, E, and H.

This study was designed to elucidate the mechanism of nephrotoxicity caused by antitumor agent tetraphosphine platinum (II) complex (RC-1), which was synthesized as a tetraphosphine Pt (II) derivatives recently. Rats treated with RC-1 (20mg/kg/day) showed the increase of BUN value and malondialdehyde contents in kidney homogenate, compared to the control and which means the lipid peroxidation was a main cause of nephrotoxicity. In order to investigate the cytotoxic mechanism of RC-1, we also tested and revealed the generation of oxygen free radicals derived from neutrophil stimulated by RC-1 and interaction of the oxygen free radicals with the erythrocyte membrane. From the above results, we suggest that nephrotoxicity of general platinum (II) antitumor compounds as well as RC-1 were inhibited by radical scavengers.
