EFFECT OF CHLORELLA AS A BIOFERTILIZER ON GERMINATION OF WHEAT AND BARLEY GRAINS

Most of the agriculture sectors have been dependent heavily on inorganic chemical-based fertilizers, which are harmful for both human health and environment. The utilization of beneficial microbes as a biofertilizer has become major concern in industrial agriculture for their potential role in food safety and sustainable crop production. In this study, we examined the effect of Chlorella on germination of barley and wheat grains. Seeds were germinated in culture medium containing microalga (Chlorella sp. 56) and grown for 3, 6, 9 and 12 days in order to study its effect on growth parameters. In conclusion, Chlorella suspension increased the seed growth compared to those of control (sterilized culture medium) of seed germination. The best treatments were 0.06 g/L and 0.23 g/L of algal suspension for the root and shoot lengths of barley and wheat seeds, respectively

Effect of Chlorella vulgaris as a biofertilizer on germination of tomato and cucumber seeds

Although inorganic fertilizers are known to raise environmental and health problems, the current agricultural practices are heavily dependent on the application of synthetic fertilizers and pesticides. In this study, we examined the effect of Chlorella vulgaris strain on germination of tomato and cucumber seeds. Seeds were germinated in culture medium containing algal strain and grown for 3, 6, 9 and 12 days to study its effect on growth parameters. As results, C. vulgaris suspension increased the seed growth compared to those of the control (sterilized culture medium) of seed germination. The best treatments were 0.17 and 0.25 g/L of algal suspension for the root and shoot lengths of tomato and cucumber seeds, respectively

Ultrasound-Guided Unilateral Posterior TAP Block for Lower Abdominal Surgery in Children

Objectives: This study aimed to evaluate the analgesic effect of ultrasound-guided transversus abdominis plane block in children. Methods: Children between 3-18 years of age on whom lower abdominal surgeries were preformed are included in this random control trial (RCT). The parents signed a written consent form. Patients were randomized into control and study groups. Every group was divided into subgroups either with or without inflammation. Results: There were no differences between the two studied groups regarding demographic and clinical characteristics. Hemodynamics were more stable in the study group than in the control group. After induction, BP decreased in all groups and increased after surgical incision except for the transversus abdominis plane elective (TAP + Elec) group. An elevated white blood cell count was used as the mean indicator of inflammation. The opioid usage during the operation was significantly different in the subgroups (p = 0.000). The relationship between WBC and opioid usage was weak, positive, and statistically significant. Postoperative pain and pain medication requirements were lower in the TAP block group. Conclusion: Transversus abdominis plane block under ultrasound guidance is easy, safe, reliable, and adequate for analgesia in children. This method can decrease surgical and postoperative pain and analgesic requirements

Association of Serum Iron Parameters with Activity of Liver Enzymes in Mongolian Patients with Chronic Hepatitis "C"

Objectives: The purpose of this study was to investigate the relationship between serum iron parameters with the activity of liver enzymes among patients with HCV in Mongolia. Methods: Twenty patients with HCV, who were registered at the National Center for Communicable Diseases, Mongolia, participated in our study. Serum iron and serum ferritin levels were determined using immunoassay. Hepcidin levels were analyzed using ELISA. Results: Liver enzymes, aspartate aminotransferase (ASAT) and alanine transaminase (ALAT), were 65.79 ± 0.52u/l and 51.22 ± 0.54 u/l, respectively. Serum iron levels were high (>180μg/dl) in 20% of patients, while serum ferritin levels were high in (>300ng/ml) in 25% of patients. Serum ferritin levels were strongly correlated with elevated ASAT (r = 0.62, p = 0.005) and ALAT (r = 0.53, p = 0.02). Additionally, serum iron was strongly correlated with ASAT (r = 0.61, p = 0.002) and ALAT (r = 0.53, p = 0.02). No correlation was identified between ASAT or ALAT and hepcidin. Conclusion: ALAT and ASAT levels were directly associated with increased levels of serum iron, but not serum ferritin. Serum hepcidin levels may affect ASAT levels

Some Physiological and Biochemical Properties of Microalgae in Vegetable Soil

Chlorella is included in a group of an autotrophic protococci alga and is occurred in ponds, wells, moist soil and on the surface of trees. It is circular in shape, 1.5-10.5μm in size and is a unicellular alga (1). Among them, some strains of Chlorella genus contain 45-50% protein, 20- 25% carbohydrate, 7-10% lipids, and biologically active substances such as several types of vitamins and essential amino acids, hence, other countries are widely utilizing them in food, forage, pharmaceutical and cosmetic purposes (1.7). Other countries are searching for chances to isolate a microalgae strain from their natural resources which can synthesize biologically active substances, to determine their properties, to utilize them practically and to produce their biopreparations by biotechnological methods (1.2.7). Therefore, we studied the physiological and biochemical properties of the cultures that were isolated from the soil of a greenhouse in order to detect a biologically active microalgae strain.DOI: http://dx.doi.org/10.5564/pmas.v0i4.51 Proceedings of the Mongolian Academy of Sciences 2009 No.4 pp.86-8

Identification and characterization of leaf rust (Puccinia triticina) and Fusarium head blight (Fusarium graminearum) related genes in domesticated wheat varieties in Mongolia

Wheat is recognized as the major crop among all cereals. For better quality and disease-free production, the current study was designed to evaluate the prevalence of genetic leaf rust resistance and fusarium head blight in nineteen genotypes of wheat, which are commonly grown in Mongolia. For example Khalkhgol-1, Darkhan-131, Darkhan-160, Darkhan-144, Orkhon, Darkhan-34, Darkhan-74, Darkhan-193, Altaiskaya-100, Darkhan-181, Darkhan-141, Buryatskaya osistiya, Darkhan-166, Buryatskaya-79, Buryatskaya-34, Selenge, Altaiskaya-530, Altaiskaya-325 and Altaiskaya jinitsa genotypes. The presence of Lr34 and Fhbt1 genes were evaluated for leaf rust and fusarium head blight respectively. Lr34 gene was reported in the Darkhan-160 and Darkhan-181 genotypes, while fusarium head blight was not reported in any of the genotype

Ranges for Reticulocyte Fractions and Reticulocyte Hemoglobin of Mongolian Donors

Objectives: The goal of this study was to determine the performance of reticulocyte fractions and reticulocyte hemoglobin for early detection of iron deficiency and iron deficiency anemia among Mongolian blood donors. Methods: Blood samples were collected before and after blood donations and analyzed using a Sysmex XN- 2000 analyzer. Iron levels (Umol/L) and Ferritin levels (µmol/L) were measured using a COBAS E601 (ROCHE, Japan). Results: Anemia was diagnosed in 3.2% all of the donors. In donors with anemia the results were: HGB 10.6±0.6 g/dl, serum ferritin 5.5 (4; 9) µmol, serum iron 5.7 (4; 7) µmol and Ret-He 26.5 (23; 28) pg. The mean value of reticulocyte was 1.2±0.3 and 1.1±0.3 within a reference range of 0.5-2%. The mean values of IRF before and after blood donations were 6.3±2.6 and 5.9±2.7 respectively with range of 1.1 - 15.9%. There were no clear differences in reticulocyte count and its fractions among donors before and after blood donation. The mean Ret-He was 32.1+1.7 pg before blood donation; 31.2+2.2 pg 28 days after donation and 31.7+ 1.6 pg within 2-3 months after the first blood donation. There are significant differences in RET-He between the before and after blood donations. Conclusion: IRF and Ret-He are very useful parameters for estimating hematopoiesis, monitoring for iron treatment and early detection of iron deficiency
