The present study aimed to study the cytotoxic effects of three Iraqi traditional medical plants extracts using tissue culture teqnique on the human hepatocarcinoma HepG2 and mouse cell L20B cell lines. Glycyrrhiza glabra L. root, Morus nigra L. and Urtica urens L. leaves were extracted using 99% ethanol solvent. Seven crude concentrations were prepared by serial dilution, with concentrations of 3.9, 7.81, 15.62, 31.25, 62.5, 125 and 250 mg/ml, respectively. These were added to the microtiter plate containing 1x105 cells/well and 200 µl of the medium. The seven concentrations were used in triplicate to investigate their cytotoxic and anti-proliferative effects. The analysis of chemical composition of these plant extracts were determined by fast liquid chromatography (FLC). The extract of Urtica urens L showed the highest potent cytotoxicity in the HepG2 and L20B cell lines, while both G. glabra L. and Morus nigra L. crude extracts showed the lowest cytotoxicity. All concentrations of crude extracts showed different cytotoxic activity in vitro.

Objective/ Background: Cancer is still the most common cause of morbidity in world and new powerful anticancer agents without severe side effects from natural sources is important. Methods: The evaluation of cytotoxicity and apoptosis induction was carried out in MCF-7,HeLa and Saos-2 as cancerous cell lines with different histological origin and human fibroblast served as control normal cell. The cells were treated with different concentrations of chitosan and the cytotoxicity was determined using MTT assay after 24, 48 and 72 h .The mode of death was evaluated by flow cytometry . Results: While both types of chitosan showed significant concentration-dependently cytotoxic effects against the three cancerous cell lines, fibroblast cells showed somehow more compatibility with chitosan. On the other hand, there were no significant differences between LMWC and HMWC cytotoxicity in all cell lines. The flow cytometry results showed the apoptosis pattern of death more in Saos-2 and HeLa while necrosis was more observable with MCF7. Also higher viability with both types of chitosan was seen in fibroblast as normal cells Conclusion: Chitosan shows anticancerous effect against 3 cancerous cell lines, while it is compatible with normal diploid fibroblast cells. Furthermore, it seems that the molecular weight of chitosan does not affect its anticancerous property.

The radiolabeled anti-T cell antibody T101 can be used for specific tumor localization, but unlabeled T101 produces limited cytotoxicity in patients. We thus studied the in vitro cytotoxic effects of T101 labeled with 125I, a radionuclide known for its short-range, high- linear-energy electrons. We showed that 125I-T101 could be readily prepared at high specific activity with high immunoreactivity. Human malignant T cell lines HUT 102, MOLT-4, and HUT 78 were found to differ in the number of T65 determinants (the antigen recognized by T101) and the sensitivity to external x-ray radiation, which were of significance for the cytotoxicity of 125I-T101 in vitro. The cytotoxic effects of 125I-T101 were also found to be dose dependent and increased with exposure time under frozen conditions. As controls, unlabeled T101 had no cytotoxic effect, while free Na 125I or the 125I-labeled irrelevant antibody 9.2.27 exerted minor cytotoxicity. In HUT 102 and MOLT-4, more than 3 logs' cell killing was achieved within four weeks. Because considerable cytotoxicity was demonstrated in vitro by 125I-T101 on T65- positive malignant cells, and because low-dose 111In-T101 can be used successfully for tumor localization, future trials using 125I-T101 at high specific radioactivity may improve therapeutic results in patients with T65-positive malignancies.

Bladder Cancer Recurrence

Abstract Urinary bladder cancer is a common cancer worldwide. Currently, the modality of treating and monitoring bladder cancer is wide. Nonetheless, the high recurrence rate of non-muscle-invasive bladder cancer after surgical resection is still unsatisfactory. Hereby, our study demonstrated whether the intra-operative and post-operative environments will affect bladder cancer recurrence utilizing in vitro cell line model. Bladder cancer cell lines were submerged in four different irrigating fluids for assessing their tumorigenic properties. Our results showed that sterile water performed the best in terms of the magnitude of cytotoxicity to cell lines. Besides, we also investigated cytotoxic effects of the four irrigating agents as well as mitomycin C (MMC) in normothermic and hyperthermic conditions. We observed that sterile water and MMC had an increased cytotoxic effects to bladder cancer cell lines in hyperthermic conditions. Altogether, our results could be translated into clinical practice in the future by manipulating the intra-operative and post-operative conditions in order to lower the chance of residual cancer cell reimplant onto the bladder, which in turns, reducing the recurrence rate of bladder cancers.
