Abstract
To treat and control parasitic infections, traditional medical remedies using plant products are utilized as antiparasitic agents rather than standard synthetic chemicals due to drug resistance. Myrrh, a resinous exudate of Commiphora myrrha (Burseraceae), is a powerful antioxidant with a variety of medicinal uses. This study aimed to investigate the effect of the myrrh methanolic extract (MyE) of three concentrations (100, 50, and 25 mg/ml) on the sporulation of oocysts and as an anthelminthic effector via in vitro study. Characterization of the plant was done by Fourier-transform infrared spectroscopy (FT-IR). The earthworm, Eisenia fetida, is used as a model worm to evaluate the anthelminthic activity of MyE. Eimeria labbeana-like oocysts are used as a model protozoan parasite in anticoccidial assays. The sporulation and inhibition (%) of E. labbeana-like were assessed by MyE compared to other chemical substances. FT-IR revealed the presence of twelve active compounds. Our results showed that paralysis and death of earthworms at MyE (100 mg/ml) were 7.88 ± 0.37 and 9.24 ± 0.60 min, respectively, which is more potency when compared to mebendazole (reference drug). In all treated worms, microscopic examinations revealed obvious surface architecture abnormality. This study shows that MyE affects oocysts sporulation in a dose-dependent manner. At 24 and 36 hr, a high concentration of MyE (100 mg/ml) inhibits sporulation by 90.95 and 87.17 %. At 36 hr, other concentrations of MyE (50 and 25 mg/ml), as well as amprolium, DettolTM, and phenol inhibits oocyst sporulation by 40.17 %, 29.34 %, 45.09 %, 85.11 %, and 61.58 %, respectively. According to our research, the MyE extract had powerful anthelmintic and anticoccidial properties.

Abstract
Commiphora myrrha, located in the tropical zone, is a widely used tree for medicinal purposes in the Arabian Peninsula and a large part of Africa. In this research, cytogenotoxic effects of the commercially available Commiphora myrrha essential oil (myrrh) were studied using micronucleus (MN), comet, and total oxidant (TOS), and total antioxidant (TAS) assays on human peripheral lymphocytes under in vitro conditions. In addition, pure pBR322 plasmid DNA was used to investigate DNA damaging/protecting activity of the essential oil. Finally, a bacterial reversion (Ames) test was performed using Salmonella typhimurium mutant strains TA98 and TA100 to determine the potential effect of the agent in the induction of gene mutations. The high concentration of Commiphora myrrha (0.125 µL/mL) induced MN formation significantly compared to the untreated control in both treatment times (24 or 48 h). Only at the highest concentration, nuclear division index (NDI) values were found lower than the controls. In the Comet test performed on healthy lymphocytes, only the highest concentration of myrrh caused significant increases in the percentage of damaged cells and genetic damage index (GDI) values. Myrrh oil showed no significant mutagenic effect on mutant Salmonella strains. In addition, the substance did not directly damage plasmid DNA but also protected DNA against damaging factors such as H2O2 and UV. Finally, in the TAS and TOS assays, no significant differences on the oxidative stress parameters were found in cell culture compared to the control. The results of this study showed that myrrh oil exerts cytogenotoxic risk only at higher concentrations.

Abstract
BACKGROUND The early period after tooth extraction is a critical period for wound healing. Wound healing after tooth extraction is considered secondary intention healing. It passes through several stages in the following order: hemostasis, inflammatory phase, proliferative phase, and finally the remodeling phase.Wounds usually heal normally unless there is interference by local or systemic factors. In certain circumstances, early wound healing can be enhanced by several interventions such as antibiotics, mouthwashes, or topical medications. Myrrh has been used as a topical medication for promoting wound healing after tooth extraction. The purpose of this study was to assess the wound healing effect of myrrh mouthwash during the early post-extraction period. METHODS We enrolled 40 healthy adult patients in this study (20: study group and 20: control group). All the activities performed for each group were double-blinded. All the participants underwent dental extraction under local anesthesia using standard protocol. Next, the study group used Commiphora molmol (myrrh) extract as a mouthwash while the control group used normal saline mouthwash. The participants used the mouthwashes twice a day for 7 days starting from the first post-extraction day. Clinical examination data were recorded and analyzed using the Mann Whitney Wilcoxon test. RESULTS There was a statistically significant between-group difference in postoperative surgical-site edema, tenderness, and socket size, with the test group showing greater improvements. CONCLUSIONS Myrrh mouthwash has an enhancement effect on wound healing during the early period after tooth extraction.

Abstract
OBJECTIVES Short-chain fatty acids are involved in the regulation of the gut immune system. In ulcerative colitis, short-chain fatty acids are often reduced, especially during flare. This study evaluated exploratively the pattern of butyrate and total short-chain fatty acids in patients with ulcerative colitis during flare treated either with mesalamine or a herbal preparation consisting of myrrh, chamomile flowers, and coffee charcoal which showed promising results in maintaining remission in a randomized double-blind, double-dummy, controlled clinical trial (EudraCT-Number 2007-007928-18). METHODS Patients were treated with the herbal preparation or mesalamine. Clinical activity was monitored by Clinical Colitis Activity Index. Using gas chromatography, we analyzed fecal samples of 38 patients who experienced a flare during treatment. RESULTS Paired t-test showed a significant decline of total short-chain fatty acids [M before = 66.12, SD = 39.59; M after = 29.83, SD = 15.05; 95% bootstrap confidence interval (20.53-55.30); P = 0.01) and of butyrate [M before 11.35, SD = 7.56; M after = 6.50, SD = 3.55; 95% bootstrap confidence interval (2.06-8.11); P = 0.02] in the event of a flare for patients treated with mesalamine but not for patients treated with the herbal preparation. CONCLUSION Patients who received the herbal preparation did not show a significant decline of total short-chain fatty acids in the event of a flare. Since a decline of short-chain fatty acids might lead to unfavorable health impairments, a combination of the two treatments should be further investigated.

Abstract
The pathogenesis of ulcerative colitis (UC) has been associated with a weakened antioxidant capacity and increased inflammatory processes. Myrrh is traditionally used for the treatment of inflammatory diseases due to its antioxidant and anti-inflammatory properties. The present study aimed to evaluate the effects of myrrh on an experimental rat model of UC. UC was induced in rats using acetic acid (AA) after pre-treatment with myrrh (125, 250 or 500 mg/kg/day) or mesalazine (MES; 300 mg/kg/day) for 7 days. The levels of various inflammatory cytokines, prostaglandin E2 (PGE2) and nitric oxide (NO) in the rat colon tissues were assessed. In addition, the colonic levels of thiobarbituric acid reactive substances (TBARS) and non-protein sulfhydryl groups (NP-SH), as well as the activities of superoxide dismutase (SOD) and catalase (CAT), were estimated. Furthermore, total protein (TP) contents and the levels of DNA and RNA were measured, and histopathological changes in colonic tissues were analyzed. The results indicated that the levels of pro-inflammatory cytokines, PGE2, NO and TBARS were markedly increased. By contrast, the levels of interleukin-10, NP-SH, TP and nucleic acids, and the enzymatic activities of SOD and CAT were significantly decreased in the AA model group. In addition, pretreatment with myrrh and MES was able to attenuate the impaired oxidative stress response and upregulation of inflammatory biomarkers. Furthermore, the enzymatic activities of SOD and CAT were near to normal in the myrrh and MES pretreated groups. The ability of myrrh to protect against UC was further confirmed by histopathological analysis, and the high dose of myrrh exerted an effect comparable to MES. In conclusion, the results of the present study suggested that myrrh has potent therapeutic value in the amelioration of experimental colitis in laboratory animals by downregulating the expression of proinflammatory mediators and improving endogenous antioxidative activities.

Abstract
BACKGROUND The herbal treatment with myrrh, dry extract of chamomile flowers and coffee charcoal has anti-inflammatory and antidiarrhoeal potential and might benefit patients with UC. Aminosalicylates are used as standard treatment for maintaining remission in ulcerative colitis (UC). AIM To compare the efficacy of the two treatments in maintaining remission in patients with ulcerative colitis. METHODS We performed a randomised, double-blind, double-dummy study over a 12-month period in patients with UC. Primary endpoint was non-inferiority of the herbal preparation as defined by mean Clinical Colitis Activity Index (CAI-Rachmilewitz). Secondary endpoints were relapse rates, safety profile, relapse-free times, endoscopic activity and faecal biomarkers. RESULTS A total of 96 patients (51 female) with inactive UC were included. Mean CAI demonstrated no significant difference between the two treatment groups in the intention-to-treat (P = 0.121) or per-protocol (P = 0.251) analysis. Relapse rates in total were 22/49 patients (45%) in the mesalazine treatment group and 25/47 patients (53%) in the herbal treatment group (P = 0.540). Safety profile and tolerability were good and no significant differences were shown in relapse-free time, endoscopy and faecal biomarkers. CONCLUSIONS The herbal preparation of myrrh, chamomile extract and coffee charcoal is well tolerated and shows a good safety profile. We found first evidence for a potential efficacy non-inferior to the gold standard therapy mesalazine, which merits further study of its clinical usefulness in maintenance therapy of patients with ulcerative colitis.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The resinous exudates of the Commiphora species, known as 'myrrh', are used in traditional Chinese medicine for the treatment of trauma, arthritis, fractures and diseases caused by blood stagnation. Myrrh has also been used in the Ayurvedic medical system because of its therapeutic effects against inflammatory diseases, coronary artery diseases, gynecological disease, obesity, etc. AIM OF THE REVIEW Based on a comprehensive review of traditional uses, phytochemistry, pharmacological and toxicological data on the genus Commiphora, opportunities for the future research and development as well as the genus' therapeutic potential are analyzed. METHODS Information on the Commiphora species was collected via electronic search (using Pubmed, SciFinder, Scirus, Google Scholar and Web of Science) and a library search for articles published in peer-reviewed journals. Furthermore, information also was obtained from some local books on ethnopharmacology. This paper covers the literature, primarily pharmacological, from 2000 to the end of December 2011. RESULTS The resinous exudates from the bark of plants of the genus Commiphora are important indigenous medicines, and have a long medicinal application for arthritis, hyperlipidemia, pain, wounds, fractures, blood stagnation, in Ayurvedic medicine, traditional Chinese medicine and other indigenous medical systems. Phytochemical investigation of this genus has resulted in identification of more than 300 secondary metabolites. The isolated metabolites and crude extract have exhibited a wide of in vitro and in vivo pharmacological effects, including antiproliferative, antioxidant, anti-inflammatory and antimicrobial. The bioactive steroids guggulsterones have attracted most attention for their potent hypolipidemic effect targeting farnesoid X receptor, as well as their potent inhibitory effects on tumor cells and anti-inflammatory efficiency. CONCLUSIONS The resins of Commiphora species have emerged as a good source of the traditional medicines for the treatment of inflammation, arthritis, obesity, microbial infection, wound, pain, fractures, tumor and gastrointestinal diseases. The resin of C. mukul in India and that of C. molmol in Egypt have been developed as anti-hyperlipidemia and antischistosomal agents. Pharmacological results have validated the use of this genus in the traditional medicines. Some bioassays are difficult to reproduce because the plant materials used have not been well identified, therefore analytical protocol and standardization of extracts should be established prior to biological evaluation. Stem, bark and leaf of this genus should receive more attention. Expansion of research materials would provide more opportunities for the discovery of new bioactive principles from the genus Commiphora.

Abstract
Myrrh has long been used for its circulatory, disinfectant, analgesic, antirheumatic, antidiabetic, and schistosomicidal properties. Myrrh essential oil (MEO) was extracted from the oleo-gum resin of Commiphora molmol and formulated into emulsions and suppositories to mask/avoid its bitter taste. Three oil-in-water emulsions (E1-E3) were formulated and taste was evaluated by 10 volunteers. Particle size distribution was measured and correlated with excipients and the method of preparation. Physical and chemical stability testing was carried out for the optimum formulation (E2). Seven suppository formulations were investigated (F1-F7). Suppocire AML (F1) and Suppocire CM (F2) were chosen as fatty bases, and polyethylene glycol (PEG) 1500 (F3), PEG 4000 (F4), and a PEG blend (50% PEG 6000 + 30% PEG 1500 + 20% PEG 400) (F5) were chosen as water-soluble bases. A blend of PEG 1500 and Suppocire CM was also used (F7). Camphor (5%) was added to PEG 1500 (F6). Disintegration time, release rate, DSC, fracture points, and weight uniformity were evaluated. The overall average bitterness for formulations E1, E2, and E3 was 6.44, 4.15, and 3.45, respectively. Suppositories containing Suppocire AML had the fastest disintegration time (1.5 min) with dissolution efficiency (DE) of 56.8%. F3 containing PEG 1500 had a fast disintegration time of 2.5 min and maximum DE of 93.5%. The PEG blend had satisfactory release: (DE = 90.9%). A mixed fatty and water-soluble base (F7) had a disintegration time of 5 min and low DE (33.4%). A stable MEO emulsion with acceptable taste was formulated to improve patient acceptance and compliance. F3 suppositories yielded satisfactory results, while formulations containing fatsoluble bases exhibited poor release.

Abstract
Myrrh has been used as an antibacterial and anti-inflammatory agent. However, effect of myrrh on peritoneal macrophages and clinically relevant models of septic shock, such as cecal ligation and puncture (CLP), is not well understood. Here, we investigated the inhibitory effect and mechanism(s) of myrrh on inflammatory responses. Myrrh inhibited LPS-induced productions of inflammatory mediators such as nitric oxide, prostaglandin E2, and tumor necrosis factor-α but not of interleukin (IL)-1β and IL-6 in peritoneal macrophages. In addition, Myrrh inhibited LPS-induced activation of c-jun NH2-terminal kinase (JNK) but not of extracellular signal-regulated kinase (ERK), p38, and nuclear factor-κB. Administration of Myrrh reduced the CLP-induced mortality and bacterial counts and inhibited inflammatory mediators. Furthermore, administration of Myrrh attenuated CLP-induced liver damages, which were mainly evidenced by decreased infiltration of leukocytes and aspartate aminotransferase/alanine aminotransferase level. Taken together, these results provide the evidence for the anti-inflammatory and antibacterial potential of Myrrh in sepsis.

Abstract
Boswellic acid (BA), a triterpene, isolated from Boswellia serrata (Burseraceae) has been found to possess potent anti-inflammatory and anti-cancer activity. The present study aimed at exploring the possible role of BA on ascites and solid Ehrlich tumor. Ascitic tumor development was evaluated 14 d after tumor implantation by quantification of the ascitic fluid volume whereas solid tumor was evaluated after 30 d tumor implantation by H&E and IHC. The i.p. administration of BA significantly inhibited ascitic and solid Ehrlich tumor model. This inhibition was observed with reduced ascitic volume, solid tumor volume and body weight when compared to control mice. The treatments also increased the survival of tumor-bearing mice. VEGF and TNF- α levels were decreased, whereas the IL-12 levels were increased with BA treatment at 25mg/kg. Further, results on decrease in the peritoneal angiogenesis and microvessel density showed the anti-angiogenic potential. Microscopic examination of tumors revealed that in BA-treated groups the expression of Bax and caspase 3 increased, suggesting drug induced tumor cell apoptosis through activating the pro-apoptotic bcl-2 family and caspase-3. The present study sheds light on the potent antitumor property of the boswellic acid and can be extended further to develop therapeutic protocols for treatment of cancer.

Abstract
Myrrh (Commiphora molmol) has been widely used as an anti-inflammatory and wound healing commercial product. As white blood cell (WBC)/leukocyte counts have been used as an indicator by clinicians to monitor progress of healing in patients, the purpose of this study was to examine effects of myrrh supplementation on blood WBC numbers before an injury and during healing. Male rats (7-8-wk-of-age) were randomly assigned to four groups. Group 1 (SIM) served as "skin injury treated + myrrh treatment (500 mg/kg/day)," Group 2 (SI) as "skin injury alone", Group 3 (GUM) as "gastric ulcer treated + myrrh treatment", and Group 4 (GU) as gastric ulcer only. Myrrh treatments (via drinking water) began 4 wk before induction of injury and continued for a 2 wk period post-injury. Baseline values for each WBC type were recorded before start of the myrrh treatments. Counts were performed again on Day 1 of the 5th wk (1-2 hr before injury) and post-injury on Days 4 and 7 of the 5th wk, and a final time on Day 4 of the 6th wk. Results showed that levels of all WBC types were significantly (P < 0.05) elevated before either injury in myrrh-treated rats (Groups 1 and 3) as compared with levels in rats in Groups 2 and 4. At all timepoints, there were neither significant differences between the values seen with rats in Groups 1 and 3, nor between those in Groups 2 and 4. Treatment with myrrh also induced an initial increase in WBC levels that persisted through the post-injury healing period. Levels of most cell types only increased in the Group 2 and 4 rats once the injury was induced, but then declined over the healing period. Since myrrh enhanced WBC levels before injury, we conclude that myrrh likely contains substances that could induce an apparent antigen-driven response. As the myrrh also helped maintain elevated WBC levels throughout the healing period, this implied it was also able to induce maturation/differentiation/activation of both myeloid and lymphoid cell types during the effector phase of the immune responses involved in wound healing.

Abstract
The possible role of Commiphora molmol emulsion (CME) in protecting against lead (PbAc)-induced hepatotoxicity, oxidative stress and immunotoxicity in rabbits was assessed. Six groups of animals were used: groups I (control) and II (PbAc) were not supplemented with CME. Groups III (CME50) and IV (CME50+PbAc) were administered with CME in a dose rate of 50mg/kg bwt, while groups V (CME100) and VI (CME100+PbAc) were received 100mg CME/kg bwt daily p.o for successive 14 weeks. Groups II, IV and VI were given 80 mg PbAc/kg bwt/day orally for 6 weeks starting from the 9th week. At the 12th week, animals were subjected to immunization by a single dose of sheep RBCs. The PbAc-group showed 220% increase in hepatic malondialdehyde levels, while glutathione, glutathione s-transferase and glutathione peroxidase levels decreased. Lead-acetate induced hypoproteinemia and hypoalbuminemia, and increased aminotransferases activity. It reduced the values of lymphocyte transformation test, phagocytic activity, phagocytic index and antibody titer against sheep SRBCs. Interestingly, pretreatment with CME attenuated these adverse effects in a dose-dependent protection. CME, therefore, is a potent antioxidant, and can protect against PbAc-induced hepatic oxidative damage and immunotoxicity by reducing lipid peroxidation and enhancing the antioxidant and immune defense mechanisms.

Abstract
There is growing use of anticancer complementary and alternative medicines (CAMs) worldwide. The purpose of the current study is to assess a sizeable variety of natural and plant sources of diverse origin, to ascertain prospective research directives for cancer treatment and potential new chemotherapy drug sources. In this study, 374 natural extracts (10 microg/mL-5 mg/mL) were evaluated for dose-dependent tumoricidal effects using immortal neuroblastoma of spontaneous malignant origin. The findings indicate no pattern of tumoricidal effects by diverse plants with similar families/genus under the classes Pinopsida, Equisetopsida, Lycopodiosida, Filicosida, Liliopsida Monocotyledons or Magnoliopsida Dicotyledons. The results indicate that many of the most commonly used CAMs exhibited relatively weak tumoricidal effects including cats claw, astragalus, ginseng, echinacea, mistletoe, milk thistle, slippery elm, cayenne, chamomile, don quai, meadowsweet, motherwort and shepherd's purse. The data demonstrate that the most potent plant extracts were randomly dispersed within the plantae kingdom (LC(50) = 31-490 microg/mL) in order of the lowest LC(50) Dioscorea villosa (Dioscoreaceae) > Sanguinaria canadensis (Papaveraceae) > Dipsacus asper (Dipsacaceae) > Populus balsamifera (Salicaceae) > Boswellia carteri (Burseraceae) > Cyamopsis psoralioides (Fabaceae) > Rhamnus cathartica (Rhamnaceae) > Larrea tridentate (Zygophyllaceae) > Dichroa febrifuga (Hydrangeaceae) > Batschia canescens (Boraginaceae) > Kochia scoparia (Chenopodiaceae) > Solanum xanthocarpum (Solanaceae) > Opoponax chironium (Umbelliferae) > Caulophyllum thalictroides (Berberidaceae) > Dryopteris crassirhizoma (Dryopteridaceae) > Garcinia cambogia (Clusiaceae) > Vitex agnus-castus (Verbenaceae) > Calamus draco (Arecaceae). These findings show tumoricidal effect by extracts of wild yam root, bloodroot, teasel root, bakuchi seed, dichroa root, kanta kari, garcinia fruit, mace, dragons blood and the biblically referenced herbs: balm of gilead bud, frankincense and myrrh gum.

Abstract
Anthracycline antibiotics, particularly doxorubicin (DOX) and daunorubicin, have been used extensively in the treatment of human malignancies. However, cardiotoxicity and multidrug resistance are significant problems that limit the clinical efficacy of such agents. Rational design to avoid these side effects includes strategies such as drug targeting and prodrug synthesis. The DOX prodrug N-(beta-D-glucopyranosylbenzyloxycarbonyl)-doxorubicin (prodrug 1) was synthesized for specific activation by beta-galactosidase, which is expected to release in necrotic areas of tumor lesions. Described here is the safety, pharmacokinetics, and biodistribution studies of a beta-galactoside prodrug of DOX. In vivo safety evaluation was done in the Ehrlich Ascites Carcinoma (EAC) tumor model. The dose of DOX was 8 mg/kg and the dose of prodrug was 8 mg/kg and 24 mg/kg of DOX equivalents. Our results on cytotoxicity, which demonstrated compression in the number of EAC cells and their viability, substantiate these data. Prodrug 1 was safe up to a dose of 24 mg/kg of DOX equivalents in EAC mice. The pharmacokinetics and biodistribution of prodrug (300 mg/kg) in normal mice were determined and compared with DOX (20 mg/kg). Administration of DOX in normal mice resulted in a peak plasma concentration of 19.45 microM (t = 30 minutes). Prodrug injection resulted in 3- to 16-fold lower concentrations in the tissues of normal mice. As it is more polar, lower levels were observed in tissues and plasma in contrast to the parent compound DOX. In vivo safety studies have shown that prodrug 1 had a maximum tolerated dose compared with DOX and led to improved pharmacokinetics in normal mice.

Abstract
The effects of lead acetate in the diet (0.5% w/w) on reduced GSH, activity of phase II metabolizing enzyme glutathione S-transferase (GST), lipid peroxidation in liver homogenate and bone marrow chromosomes of mice simultaneously supplemented with powdered turmeric and myrrh for 8 weeks were investigated. Five groups of Swiss male albino mice, each of 30 mice, the first group received a basal diet and served as negative control, the second group received basal diet supplemented with lead acetate only and served as positive control. The other three groups received basal diet supplemented with lead acetate and 1% or 5% turmeric powder and 1% myrrh powder, respectively. Results revealed a significant decrease in the amount of GSH in all treated groups compared with negative control. Also, the activity of GSH S-transferase was significantly decreased in positive control compared with other groups. However, co-administration of the protective plants resulted in a significant increase in the activity of GST compared with both positive and negative control groups. Furthermore, lipid peroxidation was significantly increased in positive control alone, while co-treatment with the protective plants resulted in reduction in the level of lipid peroxidation by 31% and 49% in mice receiving 1% and 5% turmeric powder respectively and 45% in 1% myrrh treated when compared with their respective positive control group. Lead genotoxicity was confirmed through significant reduction in the number of dividing cells, increased total number of aberrant cells and increased frequency of chromosomal aberrations. Simultaneous treatment with these plants significantly reduced the genotoxicity induced by lead administration and the powerful protection was observed with 5% powdered turmeric. It may be concluded that turmeric and myrrh are useful herbal remedies, especially for controlling oxidative damages and genotoxicity induced by lead acetate intoxication.

Abstract
Accumulating evidence suggests that the androgen receptor (AR) may play an important role in the development and progression of prostate cancer. To find new, useful compounds that effectively may attenuate the function of AR in prostate cancer cells, the authors investigated the effect of gum mastic, a natural resin, on AR activity. An androgen-responsive prostate cancer cell line LNCaP was used as a model for this study. Gene transfer, reverse transcriptase-polymerase chain reaction analysis, electrophoretic mobility shift assay, and Western blot analysis were used to test the effect of gum mastic on the expression and function of the AR. To demonstrate the inhibitory effect of gum mastic on the function of the AR, the expression of androgen-regulated genes, including prostate-specific antigen (PSA), human kallikrein 2 (hK2), and NKX3.1 were measured. In addition, transient transfection assays with the PSA promoter and the AR promoter also were used to test the effects of mastic. The results showed that gum mastic inhibited the expression of the AR at the transcriptional level, resulting in the down-regulation of both AR messenger RNA and protein levels. Therefore, the function of the AR was inhibited, as reflected by the reduced expression of NKX3.1 and PSA and by androgen-stimulated growth. Because gum mastic exhibited a strong in vitro potency to attenuate the expression and function of the AR, further investigation will be required to determine whether this naturally occurring substance has in vivo potency to inhibit prostate cancer development.

Abstract
C/EBP beta (CCAAT/enhancer-binding protein beta) is an important transcription factor involved in cellular proliferation and differentiation. Overexpression of the full-length C/EBP beta protein results in cellular growth arrest and apoptosis. Using a nonviral liposome as carrier, we delivered the full-length C/EBP beta expression plasmid, pCN, into nude mice bearing CW-2 human colon cancer tumors via tail vein. Southern blots revealed that the major organs and tumors were transfected. Experimental gene therapy showed that a strong suppression of tumor growth was observed in the pCN-treated mice, and such suppression was due to the overexpression of C/EBP beta, leading to the increased apoptosis in tumors of pCN-treated mice. No apparent toxic effects of pCN/liposome complex were observed in the animals. Thus, C/EBP beta has tumor suppression effect in vivo and may be used in gene therapy for cancers.

Abstract
The influence of boric acid, a boron carrier, on Ehrlich ascites carcinoma (EAC) cell-bearing mice was investigated in view of its importance in the boron neutron capture therapy and the influence of boron on proliferation and progression of cancer cells mediated by proteoglycans and collagen. The present study included the evaluation of boric acid for the effects on total count and viability of EAC cells in addition to their non-protein sulfhydryls (NP-SH) and malondialdehyde (MDA) contents as parameters for conjugative detoxication potency and possible oxidative damage. The EAC cell-bearing animals were also observed for the effect on survival, body weight changes, and histopathological evaluation of the tumors grown at the site of inoculation. The treatment with boric acid significantly increased the total number of peritoneal EAC cells and their viability. A significant increase in the body weight was observed that dose-dependently reached plateau levels by 20 days of treatment. Conversely, a reduction in the duration of survival of these animals was evident with the same protocol. Boric acid treatment resulted in a decrease in NP-SH contents with a concomitant increase in MDA levels in EAC cells as revealed by the results of the biochemical analysis. These data are supported by our results on histopathological investigations, which apparently showed fast growth, in addition to several mitotic figures and mixed inflammatory reaction, after treatment with boric acid. It seems likely that a particular combination of properties of boric acid, rather than a single characteristic alone, will provide useful information on the use of this boron carrier in neutron capture therapy.

Abstract
Acute (24 h) and chronic (90 days) oral toxicity studies on Commiphora molmol (oleo-gum-resin) were carried out in mice. Dosages in acute study were 0.5, 1.0 and 3 g/kg, while in chronic study dosage was 100 mg/kg per day. All external morphological, biochemical and haematological changes, in addition to body and vital organ weights were recorded. There was no significant difference in mortality in acute or chronic treatment as compared to controls. At the end of the treatment, weight gain in the treated as well as control group was significant. There was a significant increase in weight of testes, caudae epididymides and seminal vesicles in C. molmol treated group. Biochemical studies revealed no differences in C. molmol treated animals, however, haematological studies revealed a significant increase in RBC and haemoglobin levels as compared to the control group. C. molmol failed to show any spermatotoxic effects.

Abstract
Ninhydrin (2,2-dihydroxy-1,3-indane dione) was evaluated for its antitumor and cytotoxic properties in Ehrlich ascites carcinoma cell (EAC Cell)-bearing mice. The rationale behind this study has been mainly the literature reports of its characteristic interference with DNA synthesis and calcium homeostasis. Antitumor activity was evaluated from the total count and viability of EAC cells in addition to their nucleic acid, protein, non-protein sulfhydryls (NP-SH) and malondialdehyde (MDA) contents. The EAC cell-bearing animals were also observed for the effect on their survival and body weight variations. In addition, the tumors grown at the site of injection were evaluated for histopathological changes. Ninhydrin treatments (5, 10 and 20 mg/kg/day) abate the increase in body weight and advanced the duration of survival in EAC cell-bearing mice. The results on histopathological investigations show retardation in tumor growth, decreased frequency of mitotic figures and hair follicles and an increased necrosis in the tumor by ninhydrin treatment. Our results on cytotoxicity, which demonstrated compression in the number of EAC cells and their viability substantiate these data. The results of biochemical studies on EAC cells exhibit a reduction in the levels of DNA, RNA, proteins and NP-SH with a subsequent increase in the concentrations of MDA after ninhydrin treatment. Inhibition in tumor growth was dose dependently significant with the same dose regimen. The observed cytotoxic and antitumor activity of ninhydrin was comparable to cyclophosphamide. The possible mode of action of ninhydrin-induced cytotoxic and antitumor activity appear to be due to its interference with mitochondrial function resulting in inhibition of DNA synthesis, an effect that is being investigated further.

Abstract
The aqueous suspension of Commiphora molmol (oleo-gum resin) has been screened for its potential to protect gastric mucosa against the ulcers caused by 80% ethanol, 25% NaCl, 0.2 M NaOH, indomethacin and combined indomethacin-ethanol treatment. C. molmol pretreatment at doses of 250, 500 and 1000 mg/kg provided dose-dependent protection against the ulcerogenic effects of different necrotizing agents used. The effects caused by ethanol were further investigated. Treatment of rats with 1 ml of 80% ethanol was found to cause depletion of stomach wall mucus, reduction in the concentration of protein, nucleic acids and NP-SH groups in the stomach wall. Ethanol treatment also caused histopathological lesions including necrosis, erosion, congestion and haemorrhage of the stomach wall. Pretreatment with C. molmol offered a dose-dependent protection against all these effects. In the same manner it affected the malondialdehyde concentration altered by ethanol treatment. C. molmol also offered protection against mucosal damage caused by indomethacin and its combination with ethanol. The protective effect of C. molmol observed in the present study is attributed to its effect on mucus production, increase in nucleic acid and non-protein sulfhydryl concentration, which appears to be mediated through its free radical-scavenging, thyroid-stimulating and prostaglandin-inducing properties.
