Abstract
The genus Cetraria s. str. (Parmeliaceae family, Cetrarioid clade) consists of 15 species of mostly erect brown or greenish yellow fruticose or subfoliose thallus. These Cetraria species have a cosmopolitan distribution, being primarily located in the Northern Hemisphere, in North America and in the Eurasia area. Phytochemical analysis has demonstrated the presence of dibenzofuran derivatives (usnic acid), depsidones (fumarprotocetraric and protocetraric acids) and fatty acids (lichesterinic and protolichesterinic acids). The species of Cetraria, and more particularly Cetraria islandica, has been widely employed in folk medicine for the treatment of digestive and respiratory diseases as decoctions, tinctures, aqueous extract, and infusions. Moreover, Cetraria islandica has had an important nutritional and cosmetic value. These traditional uses have been validated in in vitro and in vivo pharmacological studies. Additionally, new therapeutic activities are being investigated, such as antioxidant, immunomodulatory, cytotoxic, genotoxic and antigenotoxic. Among all Cetraria species, the most investigated by far has been Cetraria islandica, followed by Cetraria pinastri and Cetraria aculeata. The aim of the current review is to update all the knowledge about the genus Cetraria covering aspects that include taxonomy and phylogeny, morphology and distribution, ecological and environmental interest, phytochemistry, traditional uses and pharmacological properties.

Abstract
BACKGROUND Diabetes Mellitus (DM) is a progressive metabolic disorder. OBJECTIVE The aim of this study was to investigate the relationship between antioxidant and oxidative stress markers in the saliva of patients with type 2 DM and a healthy control group. METHODS In this study, 20 patients with diabetes and 20 healthy individuals were evaluated. Salivary antioxidants markers consisted of total antioxidant capacity (TAC), uric acid (UA), peroxidase and catalase. Oxidative stress markers included total oxidant status (TOS), malondealdehyde (MDA) and total thiol (SH). Sialochemical analysis was performed with spectrophotometric assay. All the statistical analyses were conducted using STATA software. RESULTS TAC decreased significantly in patients with diabetes. Although salivary UA and peroxidase were lower in patients with diabetes compared to the control group, the difference was not significant. Salivary catalase in patients with diabetes was significantly lower than that in the control group. MDA and TOS exhibited significantly higher levels in type 2 DM. SH levels were slightly higher in DM. CONCLUSION According to the results of the present study, there were some changes in the salivary levels of some antioxidants and oxidative stress markers in patients with type 2 DM and could be measured as an indicator of serum changes.

Abstract
In the present study, we investigated cytogenetic and oxidative [total antioxidant capacity (TAC), total oxidant status (TOS)] effects of methanol and water extracts of Cladonia chlorophaea (Flörke ex Sommerf.) Sprengel, Dermatocarpon miniatum (L.) W.Mann and Parmelia saxatilis (L.) Ach. on cultured human lymphocytes. In addition, different phenolic compounds in the extracts were quantified by high performance liquid chromatography (HPLC) analysis. As a result of HPLC analysis, methanol extracts of all lichen species tested had higher phenolic compounds. Likewise, methanol extracts of each lichen increased TAC levels in lymphocytes more than water extracts. The TOS levels of the cells treated with different concentrations (1-100 mg/L) of the extracts decreased due to the increasing concentration of the extracts. Genotoxicity experiments revealed that the tested lichen extracts did not significantly increase (p > 0.05) the level of genotoxicity on human peripheral lymphocyte culture compared to the negative control group. The results showed that C. chlorophaea, D. miniatum and P. saxatilis lichens, which were found to be a rich source of phenolic compounds, might be of interest in the pharmaceutical and food industries.

Abstract
BACKGROUND AND OBJECTIVE Ocimum gratissimum (OG) has been used in ethnopharmacology for the treatment of diabetes. The aim of the study was to evaluate the effect of Ocimum gratissimum leaf-extract on hematological indices and lipid profile of Streptozotocin-induced diabetic Wistar rats. MATERIALS AND METHODS Twenty-four rats weighing 100-160 g were randomly assigned to four treatment groups, the normal and diabetic controls, received a placebo treatment, while groups three and four were administered glibenclamide and OG leaf-extract (400 mg kg-1 b.wt.), respectively. The extracts were administered twice daily for 28 days. The rats were sacrificed and whole blood was collected for hematological and serum lipid profile assays. Data were analyzed using one-way ANOVA. RESULTS Diabetes induction resulted in decreases (p<0.05) in Red Blood Cell (RBC), Hemoglobin (Hb), White Blood Cell (WBC) and increases in Mean Corpuscular Hemoglobin and Blood platelets compared to the normal control. Treatment with O. gratissimum extract reversed RBC (7.74±0.39 μL), WBC (16.57±3.02) and Platelet (804.33±194.02) levels, but not Hb, towards normal levels (7.99±0.04, 11.27±0.69, 839.67±10.17 respectively). Diabetes induction also resulted in increases (p<0.05) in Triglyceride (TG) and Very-Low-Density Lipoprotein (VLDL), decreases (p<0.05) in High-Density Lipoprotein (HDL) and Low-Density Lipoprotein (LDL) compared to normal control with no significant change in Total Cholesterol (TC). After administration with Ocimum gratissimum TC, LDL and VLDL and HDL levels were significantly (p<0.05) reduced relative to the diabetic control. TG was however increased relative to the diabetic control. CONCLUSION Overall, data suggests the plant holds great potential in amelioration of diabetes-induced dyslipidemia and hematological disorders.

Abstract
BACKGROUND World Health Organization statistics identifies that there are about 150 million people with diabetes mellitus worldwide and suggest that this figure may double by 2025. OBJECTIVE This research was conducted to determine the status of full blood count, zinc and manganese levels among Diabetic patients attending Specialist Hospital, Sokoto. METHODS The participants were divided into two groups; 58 diabetic subjects and 29 non-diabetic controls. Five milliliters of blood were collected into EDTA and plain containers for full blood count, serum zinc and manganese analysis. The FBC investigation was carried out using automated Mythic Haematology analyzer (Orphee, Switzerland) while Zn and Mn investigations were carried out using Atomic Absorption Spectrometry (AAS). The FBC, Zn and Mn status of both control and subjects were compared statistically. RESULTS The results obtained in this study showed a significant increase in RBC, PCV, Hb, Basophils, Eosinophil, Lymphocyte count and Manganese levels of diabetic subjects (p⩽ 0.05) when compared with controls. There was no statistically significant difference in the other FBC parameters and Zinc levels between diabetic subjects and non-diabetic controls (p> 0.05). There was a statistically significant difference in the Hb, PCV and lymphocyte of diabetic patients based on gender (p< 0.05). FBC, Manganese and Zinc have no effect based on age group, while other socio-demographic factors also have no effect on the FBC, Manganese and Zinc parameters of diabetic patients. The study also showed no statistical difference in the FBC, Manganese and Zinc of smokers and non-smokers (p> 0.05, respectively). In conclusion, this research shows that some haematological parameters (RBC count, Basophils, Eosinophil, Lymphocyte, Hb and Manganese) of the diabetic patients are significantly higher compared to non-diabetic controls. Marital status had a significant effect on the Hb, PCV and Lymphocyte of the diabetic patients (p< 0.05). The age group had no significant effect on the Hb, PCV and Lymphocyte of diabetic subjects (p> 0.05).CONCLUSIONS There is need to routinely monitor the full blood count, zinc and manganese levels among diabetic subjects in the area to optimize the care offered to these patients.

Abstract
Abstract
The present study aims at assessing the efficacies of olivetoric acid (OA) and physodic acid (PA) isolated from Pseudevernia furfuracea (L.) Zopf (Parmeliaceae) in human lymphocytes (HLs) in vitro. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and lactate dehydrogenase assays were performed to establish cytotoxicity in HLs. Besides, oxidative stress and genotoxicity were monitored by estimating the changes of total oxidative stress (TOS) and 8-hydroxy-2′-deoxyguanosine (8-OH-dG) levels, respectively, in HLs. At the same time, OA- and PA-induced total antioxidant capacity (TAC) levels in HLs were determined. Although especially low concentrations of OA (IC50=109.94 mg/L) and PA (IC50=665.49 mg/L) did not show cytotoxic effect at high levels in HLs, it was revealed that cytotoxicity was significantly (p<0.05) associated with oxidative stress and genotoxicity via correlation analysis. While TOS level in HLs did not statistically (p>0.05) increase in the presence of all treatments (0.5–100 mg/L) of PA, TAC level was increased by PA applications in certain concentrations (0.5–10 mg/L). Overall, the obtained data indicate that OA and especially PA as lichen compounds that do not cause oxidative stress can be a new resource of therapeutics as recognized in the present study with their high antioxidant features.

Abstract
Background: Effective long-term management is the key to treatment of diabetes mellitus (DM) and its complications. Aim: To ascertain the ability of cryptolepine (CRP) in managing DM and some associated complications. Materials and Methods: Changes in fasting blood sugar (FBS), body weight, response to thermally-induced pain, and semen quality were assessed in normal and alloxan-induced diabetic rats treated with CRP (10, 30, or 100 mg/kg), glibenclamide (10 mg/kg), or normal saline (2 ml/kg) per os. Hematological profile, liver and kidney function tests, lipid profile, as well as liver, kidney, and pancreas histopathological examinations were also conducted to establish possible effects of CRP treatment. Results: CRP treatment reduced (P ≤ 0.001) FBS and body weight, inhibited (P ≤ 0.05 - 0.001) the latency to tail flick or withdrawal from pain stimulus. It did not alter (P > 0.05): Hematological parameters, elevated (P ≤ 0.05 - 0.001) plasma aspartate transaminase, alanine transaminase, and gamma-glutamyl transferase, reduced (P ≤ 0.01) plasma urea, and elevated (P ≤ 0.001) plasma creatinine associated with DM. CRP, however, reversed (P ≤ 0.05 - 0.001) DM-associated elevation (P ≤ 0.05 - 0.001) of plasma cholesterol, triglycerides, and low-density lipoproteins, and the reduction in high-density lipoproteins. CRP (10-30 mg/kg) showed dose-dependent regeneration of β-islet cells but could not repair degenerated liver and kidney tissue. CRP worsens dose-dependently (P ≤ 0.001) reduced sperm quality associated with DM. Conclusion: CRP abolishes hyperglycemia, weight loss, cold allodynia, neuropathic pain, and hyperlipidemia as well as pancreatic β-islet cell damage associated with DM. It, however, does not improve liver and kidney damage and lowered semen quality.
