Cisplatin is one of the most effective antitumor agents currently available for cancer therapy. However, its clinical use has been limited by its severe side effects, especially nephrotoxicity. Therefore, brazilin, which has a radical scavenging effect, was given intraperitoneally to evaluate the effect on cisplatin nephrotoxicity in rats. Remarkable protective effects against nephrotoxicity of cisplatin were observed when brazilin was administered to rats simultaneously with cisplatin. Hepatotoxicity induced by combination treatment of cisplatin and brazilin was evaluated by measuring serum glutamic pyruvate transaminase and serum glutamic oxalate transaminase. Combination treatment did not affect the levels of sGPT and SGOT, and any combination treatment did not induce metallothionein in kidney. Brazilin which has radical scavenging effect directly reduced nephrotoxicity of wisplatin in vivo. Thus, it seems that nephrotoxicity of cisplatin was caused by free radicals. The present results Indicate that brazilin, when it is given with cisplatin, may provide protection against cisplatin nephrotoxicity in rats.

Cis-dichlorodiammineplatinum(II)(cisplatin) is one of the most effective antitumor agents currently available for cancer therapy. However, its clinical use has been limited by its severe side effects, especially nephrotoxicity. To evaluate the effect or radical scavengers on cisplatin nephrotoxicity in rats, cisplatin and Vitamin C were given intraperitoneally. Remarkable protective effects of Vitamin C against nephrotoxicity of cisplatin were observed when Vitamin C was administered to rats 1hr before cisplatin injection. hepatotoxicity induced by combination treament of cisplatin and Vitamin C was evaluated by measuring serum glutamic pyruvate transmainase(sGPT) and serum glutamic oxalate transminase(sGOT). Combination treatment did not affect the levels of sGPT and sGOT, and any combination treatment did not induce metallothionein biosynthesis in kidny, Vitamin C which has radical scavenging effect induce metallothionein biosynthesis in kidney. Vitamin C which has radical scavenging effect directly reduced nephrotoxicity of cisplatin in vivo. Thus, it seems that free radical is the cause of cisplatin nepthrotoxicity. Also, combination treatment did not reduce anticancer activity of cisplatin. The present results indicate that Vitamin C, when it is given with cisplatin, may provide protection against cisplatin nephrotoxicity without reducing anticancer activity.

Cisplatin is an inorganic complex formed by a central atom of platinum surrounded by chlorine and ammonia atoms in the cis position in the horizontal plane, Cisplatin is one of the most effective anticancer drug, widely used against various tumor such as testicular tumor, brain tumor, ovary tumor, bladder carcinoma, colon cancer etc. However its clinical use has been limited by nephrotoxicity, ototoxicity , gastrointestinal disturbances, myeloscrppression and allergic reactions. In these toxicities, dose related and cumulative nephrotoxicity is the major dose limit factor. So, to evaluate the protective effect of aspalactone on cisplatin nephrotoxicity in rats, both compounds were given intraperitoneally, Protective effects of aspalactone against nephrotoxicity of cisplatin were observed when aspalactone was administered to rats 1hr beforecisplatin injection. Hepatotoxicity induced by combination treatment of cisplatin and aspalactone was not observed. The present results indicate that aspalactone may provide protection against cisplatin nephrotoxicity, when it is given 1hr before cisplatin injection.

cis-Dichlorodiammineplatinum(cisplatin) is one of the most effective antitumor agents currently available for cancer therapy. However, its clinical use has been limited by its severe side effects, especially nephrotoxicity. So, to evaluate the effects of 2(3)-tert-butyl-4-hydroxyanisole(BHA) on cisplatin nephrotoxicity in rats, both compounds were given intraperitoneally. Remarkable protective effects of BHA against nephrotoxicity of cisplatin were observed when BHA was administered to rats 1hr after cisplatin injection. On the other hand pretreatment with BHA 1hr prior to cisplatin did not reduce weight loss, blood urea nitrogen and creatinine levels. Hepatotoxicity induced by combination treatment of cisplatin and BHA was evaluated by measuring serum glutamic pyruvate transaminase and serum glutamic oxalate transaminase. Combination treatment did not affect the levels of SGPT and sGOT except 1hr pretreatment. The present results indicate that BHA may provide protection against cisplatin nephrotoxicity, when it is given 1hr after cisplatin.

Cisplatin is a platinum-based chemotherapeutic drug for treating various types of cancers. However, the use of cisplatin is limited by its negative effect on normal tissues, particularly nephrotoxicity. Various mechanisms such as DNA adduct formation, mitochondrial dysfunction, oxidative stress, and apoptosis are involved in the adverse effect induced by cisplatin treatment. Several studies have suggested that neuropeptide Y (NPY) is involved in neuroprotection as well as restoration of bone marrow dysfunction from chemotherapy induced nerve injury. However, the role of NPY in chemotherapy-induced nephrotoxicity has not been studied. Here, we show that NPY rescues renal dysfunction by reducing the expression of pro-apoptotic proteins in cisplatin induced nephrotoxicity through Y1 receptor, suggesting that NPY can protect kidney against cisplatin nephrotoxicity as a possible useful agent to prevent and treat cisplatin-induced nephrotoxicity.

Cisplatin is one of the most effective antitumor agents currently available for cancer chemotherapy. However its clinical use has been limited by its severe side effects, especially nephrotoxicity. To evaluate the effect of schizandrin, one of radical scavengers and constituents of Schizandra chimensis, cisplatin and schizandrin were given intraperitoneally. Protective effect of schizandrin against nephrotoxicity of cisplatin was observed when schizandrin was administerd to rats 1,24 hr after cisplatin injection. Hepatotoxicity induced by combination treatment of cisplatin and schizandrin was evaluated by measuring sGPT and sGOT. Combination treatment did not affect the levels of sGPT and sGOT. The present result indicate that schizandrin when it is given after cisplatin, may provide protection against cisplatin nephrotoxicity without hepatotoxicity.

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.

Cisplatin is useful for various cancers including advanced testicular and ovarian cancers. However, clinical use of cisplatin has been limited due to its dose-related neplrotoxicity. Transport studies across the membrane vesicles were performed to study the cisplatin nephrotoxicity. In these experiments, after cisplatin was administered to adult male New Zealand White rabbits, basolateral membrane (BLM) vesicles were prepared from the renal cortex. Para-aminohippurate (PAH) uptakes through BLM vesicles were measured to examine the interactioln of cisplatin on the transports of the substrates. As results of the uptake experiments using the vesicle systems, cisplatin had little effects on PAH transport through BLM vesicle. In conclusion, cisplatin did not cause the damage of basolateral membranes.

Several Pt(II) and Pt(IV) complexes of N,N'-bis(2-hydroxyethyl)ethylenediamine(2-HEen) and N,N'-bis(2-chloroethyl) ethylenediamine(2-CEen) as carrier ligand were prepared. Water soluble Pt complexes were also synthesized by modification of leaving groups. The cytotoxicity of these compounds against leukemia L1210 and P388 cell in vitro were examined. The Pt complexes containing 2-CEen showed more effective cytotoxicity than those containing 2-HEen. Through the nephrotoxicity tests on the primary cultured proximal tubular cells of rabbit kidney and human kidney cells in vitro, Pt complexes with 2-CEen showed higher than those with 2-HEen which were consistent with cytotoxicity but showed very low nephrotoxicity compared with cisplatin. Also the values of BUN and creatinine in serum of Pt complexes were reduced remarkably compared with cisplatin, therefore it can be concluded that new Pt complexes seems to have much lower nephrotoxicity than cisplatin.

Cisplatin, an antitumor agent widely used in the treatment of cancers, has nephrotoxicity. This side effect is closely related to oxidative stress. In the present study, we studied to protective effect of ethanol extract of Bojungbangam-tang (EBJT) on cisplatin-induced nephrotoxicity. Bojungbangam-tang is a new herbal prescription composed of nine crude drugs. Pretreatment of EBJT prevented cisplatin-induced cytotoxicity and generation of ROS. Also, cellular GSH content and gluathione peroxidase activity were recovered by EBJT. EBJT also decreased cisplatin-induced expression of HO-1 via inhibition of ERK activation. Taken together, these results suggest that EBJT has a cytoprotective effect against cisplatin-induced nephrotoxicity through anti-oxidant activity.
