Pharmaceutical Journal 2005;0(5):16-19
Experimentation of using Cisplatin produced by Vietnam with dose of LD50=26.00 (23.21-29.12) mg/kg on injection line on peritoneum of white house-mice was monitored for a week, and the 100% mice died. Before the death, the mice often had some kinds of epilepsy. It was proved that this medicine affected on central nervous system. In terms of semi-chronic toxicity, Cisplatin with dose of 0.2mg/kg/24 hours of intravenous injections 5 days per course, with dose of 0.3mg/kg/24 hours of intravenous injection in 5 days, using two courses after 10 days changed some indexes of hematology and microscopic findings of bone marrow. After 15 days to 30 days of discontinuous injection, injuries gradually recovered

2.Study on semi-chronic toxicity of cisplatin DLTW 1 on liver and kineys
Pharmaceutical Journal 2005;0(7):23-26
Cisplatin was intravenously injected at the dose of 0.2 mg/kg (equivalent to 1/10 of the maximum non-toxicating dose in mice) four 5-day episodes with the interval of 5 days caused a slight increase in the serum creatinine and urea levels. Similar effects were also observed when cisplatin was IV administered at 0.3 mg/kg/24h for two 5-day episodes with the interval of 10 days. Other mild side effects towards liver and some organs were also observed in about 50% of the mice population. Most of the side effects significantly subdued in both groups 15 days after stopping drug, except damages in hepatic histology, which recovered more slowly

OBJECTIVE:
Chemotherapeutic drugs, such as cisplatin (CP), which are associated with oxidative stress and apoptosis, may adversely affect the reproductive system. This study tests whether administration of propolis and nano-propolis (NP) can alleviate oxidative stress and apoptosis in rats with testicular damage induced by CP.
METHODS:
In this study, polymeric nanoparticles including propolis were synthesized with a green sonication method and characterized using Fourier transform-infrared spectroscopy, Brunauer-Emmett-Teller, and wet scanning transmission electron microscopy techniques. In total, 56 rats were divided into the following seven groups: control, CP, propolis, NP-10, CP + propolis, CP + NP-10, and CP + NP-30. Propolis (100 mg/kg), NP-10 (10 mg/kg), and NP-30 (30 mg/kg) treatments were administered by gavage daily for 21 d, and CP (3 mg/kg) was administered intraperitoneally in a single dose. After the experiment, oxidative stress parameters, namely, malondialdehyde (MDA), glutathione (GSH), glutathione peroxidase (GPx), and catalase (CAT), and apoptotic pathways including B cell leukemia/lymphoma-2 protein (Bcl-2) and Bcl-2-associated X protein (Bax) were measured in testicular tissues. Furthermore, sperm quality and weights of the testis, epididymis, right cauda epididymis, seminal vesicles and prostate were evaluated.
RESULTS:
Propolis and NP (especially NP-30) were able to preserve oxidative balance (decreased MDA levels and increased GSH, CAT, and GPx activities) and activate apoptotic pathways (decreased Bax and increased Bcl-2) in the testes of CP-treated rats. Sperm motility in the control, CP, and CP + NP-30 groups were 60%, 48.75%, and 78%, respectively (P < 0.001). Especially, NP-30 application completely corrected the deterioration in sperm features induced by CP.
CONCLUSION
The results show that propolis and NP treatments mitigated the side effects of CP on spermatogenic activity, antioxidant situation, and apoptosis in rats.

BACKGROUND/AIMS: Darbepoetin alfa (DPO) exhibits comparable renoprotective effects to erythropoietin (EPO) in several animal models of acute renal injury. We examined whether DPO also attenuated renal injury in a rat model of cisplatin nephrotoxicity. METHODS: Male Spague-Dawley rats were divided into four groups: untreated, DPO-treated, cisplatin-injected, and DPO-treated cisplatin-injected. DPO pretreatment was conducted 24 hours after and just before cisplatin administration. Ninety-six hours after cisplatin administration, animals in all experimental groups were sacrificed. We examined serology; real-time reverse transcription polymerase chain reaction (RT-PCR) for TNF-alpha, Bcl-2, and MCP-1 gene expression; and Western blots for caspase-3. We also conducted terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) and light microscopy. RESULTS: Pretreatment with DPO significantly reduced the levels of blood urea nitrogen and serum creatinine, the magnitude of renal tubular epithelial damage, and renal gene expression of TNF-alpha, Fas, and MCP-1 in kidneys injured by cisplatin. Pretreatment with DPO significantly increased Bcl-2 mRNA levels in kidneys injured by cisplatin, and significantly reduced activated caspase-3 and TUNEL-positive cells. CONCLUSIONS: DPO exhibits a renoprotective effect in experimental cisplatin-induced renal injury, the mechanism of which may involve DPO antiinflammatory and antiapoptotic effects.

7.The effect of forsythiaside on the expression of c-jun induced by cisplatin in the cochlea of guinea pig.
Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2014;28(10):731-734
OBJECTIVE:
To study the effect of forsythiaside on the expression of c-jun induced by cisplatin in the cochlea of guinea pig.
METHOD:
Thirty guinea pigs were randomly divided into control group (10), cisplatin group (10) and forsythiaside group (10). The ototoxicity model was done with intraperitoneal injection of cisplatin solution (8 mg/kg per day) for 7 days. Forsythiaside (25 mg/kg per day) was injected 30 min before cisplatin solution treated in guinea pigs of forsythiaside group for 7 consecutive days. The saline instead of cisplatin was injected in normal control group. The distortion product otoacoustic emission (DPOAE) was detected before animals were killed. The expression of c-jun in cochlea of guinea pigs was detected by western blotting. The expression of c-jun mRNA in cochlea of guinea pigs was detected by reverse transcriptase polymerase chain reaction (RT-PCR).
RESULT:
DPOAE amplitudes in cisplatin group was significantly lower than in control group (P < 0.01). Compared with cisplatin group, DPOAE amplitudes in forsythiaside group was increased significantly (P < 0.05). The expression of c-jun protein and mRNA were significantly increased in cisplatin group than in control group (P < 0.01). Compared with cisplatin group, the expression of c-jun protein and mRNA were significantly decreased in forsythiaside group.
CONCLUSION
Forsythiaside can significantly reduce the side effects induced by cisplatin through down-regulating the expression of c-jun.

BACKGROUND/AIMS: We retrospectively analyzed comparative toxicities and efficacies of chemotherapy regimens in advanced gastric cancer (AGC) patients who achieved complete response (CR) after chemotherapy. METHODS: We reviewed the medical records of 1,203 patients, who were pathologically diagnosed as AGC in a single center between January 2001 and October 2007. On the basis of the Response Evaluation Criteria in Solid Tumors, CR was evaluated with abdominal computed tomography. Toxicities were evaluated using the National Cancer Institute's common toxicity criteria before each chemotherapy cycle. RESULTS: Among the 1,203 AGC patients enrolled in this study, 568 received chemotherapy and 635 received best supportive care. The major chemotherapy regimens were 5-fluorouracil, leucovorin and oxaliplatin (FOLFOX), docetaxel, cisplatin and 5-fluorouracil (DCF) and 5-fluorouracil, leucovorin and irinotecan (FOLFIRI). Among the 568 patients, 51 (9.0%) achieved CR (49 [8.6%] with FOLFOX [n=12], DCF [n=26], or FOLFIRI [n=11] and 2 [0.3%] with etoposide, leucovorin and 5-fluorouracil). For patients administered FOLFOX, DCF, and FOLFIRI, the median time to disease progression was 4 months (range, 1.8-59.5), 15 months (range, 2.9-31.2) and 10 months (range, 2.0-39.5), and the median survival times were 48 months (range, 5.9-74.0), 37 months (range, 14.0-86.0), and 30 months (range, 6.0-50.0), respectively. Grades 3-4 mucositis occurred mostly in patients administered DCF (n=8, 30.8%). Grades 3-4 leucopenia were observed in 1 (8.3%), 11 (42.3%), and 4 (36.4%) patients administered FOLFOX, DCF and FOLFIRI, respectively. No statistically significant differences were observed in the 3 regimens. CONCLUSIONS: All 3 regimens (FOLFOX, DCF and FOLFIRI) were active and tolerable. Their efficacies and toxicities were not significantly different.

OBJECTIVETo investigate the effects of high-affinity tyrosine kinase receptors TrkB, TrkC and the low-affinity neurotrophin receptor p75 in spiral ganglion cell (SGC) of cisplatin-induced ototoxicity.
METHODSThe 50 adult Wistar rats were divided randomly into 5 groups received intraperitoneal injection of cisplatin with vary dose. Control group was received equivalent volumes of saline. The group received 1 day intraperitoneal injection was cisplatin treated at a dose of 5 mg/kg and killed at next day. The group received 3 days was cisplatin treated for 3 days at same dose daily and then killed at next day. The group A received 5 days was cisplatin treated for 5 days and killed at next day. The group B received 5 days was cisplatin treated for 5 days and then were sacrificed after 7 days. The change of mRNA level of neurotrophin receptors in cochlear tissue were examined by RT-PCR. The expressing pattern of TrkB, TrkC, P75 in damaged cochlea were study by immunochemistry using antibodies against TrkB, TrkC, P75 protein.
RESULTSThe research data showed the expression of Trk B, Trk C, p75 exhibited in SGC was dynamic along with the administration lasting. The mRNA and protein level of Trk B (x(-) +/- s) at day 1 and 3 after cisplatin treatment were 0.76 +/- 0.06, 88.78 +/- 4.28, 0.82 +/- 0.09 and 91.64 +/- 4.06, with significant difference among those and other groups (P < 0.05). The mRNA and protein level of TrkC at day 1 after cisplatin treatment were 0.80 +/- 0.06 and 89.66 +/- 2.76, with significant difference among that and other groups (P < 0.05). The mRNA and protein level of p75 at the control group and cisplatin treated groups were 0.64 +/- 0.04, 55.16 +/- 3.10, 0.77 +/- 0.04, 78.46 +/- 3.86, 1.01 +/- 0.09, 105.02 +/- 6.61, 1.18 +/- 0.09, 111.10 +/- 6.08, 0.51 +/- 0.04 and 42.74 +/- 5.20, with significant difference among the control group and cisplatin treated groups (P < 0.05).
CONCLUSIONSThe expression of Trk B increased to peak at day 1 - 3 after cisplatin treatment and decreased at day 5 early and following weeks. The expression of Trk C went up to peak at day 1 after cisplatin treatment and went down during subsequently time. P75 kept a trend of continuance increased during the drug treatment and decrease at drug stopped. The expression of Trk B, Trk C and P75 may be involved in cochlear insult with cisplatin-induced. Trk B and Trk C may play an important role in the reparative process of cochlear, especially at early stage of the damage. P75 could promote SGC apoptosis in cisplatin-induced neurotoxicity.

Biliverdin (BV) has long been thought to be a cytotoxic metabolic waste product. It has also been demonstrated to have important cytoprotective functions during oxidative stress. The present study aimed to examine the cytoprotective effect of BV on NRK-52E cells, a proximal tubular cell line derived from rat kidney. Cells were treated with 50 µmol/L cisplatin for 24 h (cisplatin group) or pre-treated with BV for 30 min, then with 50 µmol/L cisplatin for 24 h (cisplatin+BV group). Those given no treatment served as a control. Cell apoptosis was evaluated by flow cytometry and cell viability by Cell Counting Kit-8 (CCK-8). The protein expressions of cleaved caspase3, Bax and Bcl-2 were assessed by Western blotting. Reactive oxygen species (ROS) levels were measured using carboxydichlorodihydrofluorescein diacetate (H2DCF). The results showed that cisplatin induced the apoptosis of NRK-52E cells, decreased cell viability, and increased the formation of ROS by upregulating the expression of cleaved caspase3 and Bax and decreasing Bcl-2 protein expression. These effects could be significantly reversed by pretreatment with BV. It was concluded that BV can protect against cisplatin-induced cell apoptosis through the anti-oxidative effects.
