Abstract
BACKGROUND Periodontal disease is associated with cardiovascular diseases because of its role in host immune-inflammatory response. Serum lipids are the commonest risk factors between periodontal disease and cardiovascular diseases. MATERIALS AND METHOD A double blinded randomised clinical trial was carried out among 45 subjects with generalised severe periodontitis. They were divided into 3-groups of 15 subjects each. Group A: 0.25% lemongrass oil mouthwash, Group B: 0.12% chlorhexidine mouthwash and Group C: Oral prophylaxis only Group. Oral examinations like assessment of Probing Pocket Depth and Clinical Attachment Loss and Bio-chemical tests like assessment of C-Reactive Protein, Total Cholesterol, High Density Lipid, Low Density Lipid and triglycerides were conducted at baseline followed by oral prophylaxis at the same visit. Reassessment of the above mentioned parameters were done after 3 months of intervention. Data so collected were subjected for statistical analysis using SPSS ver. 20.0. RESULTS A statistically significant reduction in C-Reactive Protein, Probing Pocket Depth, Clinical Attachment Loss, Total Cholesterol and Low Density Lipid level in 0.25% lemongrass oil mouthwash group was found. On comparing a statistically significant difference was observed for the post intervention scores of Probing Pocket Depth and Clinical Attachment Loss only; for Group A v/s C and Group B v/s C. CONCLUSION 0.25% Lemongrass oil mouthwash was found to be a good herbal alternative; both in the treatment of chronic periodontitis and reduction in the level of serum markers of Cardio Vascular Diseasess.

Abstract
OBJECTIVE Parenteral nutrition has been associated with metabolic and infectious complications in intensive care unit patients. The underlying mechanism for the high risk of complications is not known but may relate to the proinflammatory effects of soybean oil-based lipid emulsions, the only Food and Drug Administration-approved lipid formulation for clinical use. DESIGN Prospective, double-blind, randomized, controlled trial. SETTING Medical-surgical intensive care units from a major urban teaching hospital and a tertiary referral university hospital. PATIENTS Adult medical-surgical intensive care unit patients. INTERVENTION Parenteral nutrition containing soybean oil-based (Intralipid) or olive oil-based (ClinOleic) lipid emulsions. MEASUREMENTS Differences in hospital clinical outcomes (nosocomial infections and noninfectious complications), hospital length of stay, glycemic control, inflammatory and oxidative stress markers, and granulocyte and monocyte functions between study groups. RESULTS A total of 100 patients were randomized to either soybean oil-based parenteral nutrition or olive oil-based parenteral nutrition for up to 28 days. A total of 49 patients received soybean oil-based parenteral nutrition (age 51 ± 15 yrs, body mass index 27 ± 6 kg/m2, and Acute Physiology and Chronic Health Evaluation II score 15.5 ± 7 [±SD]), and a total of 51 patients received olive oil-based lipid emulsion in parenteral nutrition (age 46 ± 19 yrs, body mass index 27 ± 8 kg/m2, and Acute Physiology and Chronic Health Evaluation II score 15.1 ± 6 [±SD]) for a mean duration of 12.9 ± 8 days. The mean hospital blood glucose concentration during parenteral nutrition was 129 ± 14 mg/dL, without differences between groups. Patients treated with soybean oil-based and olive oil-based parenteral nutrition had a similar length of stay (47 ± 47 days and 41 ± 36 days, p = .49), mortality (16.3% and 9.8%, p = .38), nosocomial infections (43% vs. 57%, p = .16), and acute renal failure (26% vs. 18%, p = .34). In addition, there were no differences in inflammatory and oxidative stress markers or in granulocyte and monocyte functions between groups. CONCLUSION The administration of parenteral nutrition containing soybean oil-based and olive oil-based lipid emulsion resulted in similar rates of infectious and noninfectious complications and no differences in glycemic control, inflammatory and oxidative stress markers, and immune function in critically ill adults.

Abstract
We previously reported that the forest environment enhanced human natural killer (NK) cell activity, the number of NK cells, and intracellular anti-cancer proteins in lymphocytes, and that the increased NK activity lasted for more than 7 days after trips to forests both in male and female subjects. To explore the factors in the forest environment that activated human NK cells, in the present study we investigate the effect of essential oils from trees on human immune function in twelve healthy male subjects, age 37-60 years, who stayed at an urban hotel for 3 nights from 7.00 p.m. to 8.00 a.m. Aromatic volatile substances (phytoncides) were produced by vaporizing Chamaecyparis obtusa (hinoki cypress) stem oil with a humidifier in the hotel room during the night stay. Blood samples were taken on the last day and urine samples were analysed every day during the stay. NK activity, the percentages of NK and T cells, and granulysin, perforin, granzyme A/B-expressing lymphocytes in blood, and the concentrations of adrenaline and noradrenaline in urine were measured. Similar control measurements were made before the stay on a normal working day. The concentrations of phytoncides in the hotel room air were measured. Phytoncide exposure significantly increased NK activity and the percentages of NK, perforin, granulysin, and granzyme A/B-expressing cells, and significantly decreased the percentage of T cells, and the concentrations of adrenaline and noradrenaline in urine. Phytoncides, such as alpha-pinene and beta-pinene, were detected in the hotel room air. These findings indicate that phytoncide exposure and decreased stress hormone levels may partially contribute to increased NK activity.

Abstract
Lipid, oxidative and inflammatory parameters are frequently altered in dialysis patients and may be worsened by intravenous lipid emulsions (ILE). We assessed the efficacy and tolerance of olive as compared with standard soybean oil-based ILE during intradialytic parenteral nutrition (IDPN). IDPN mixtures containing amino acids, glucose, and either olive oil (OO group, n 17) or soybean oil-based ILE (SO group, n 18) were administered in a 5-week randomized, double-blind study. On days 0 and 35, patients' nutritional status was assessed by BMI, normalized protein catabolic rate, predialytic creatinine, serum albumin and transthyretin; lipid metabolism by plasma LDL- and HDL-cholesterol, triacylglycerols, phospholipids, apo A-I, A-II, B, C-II, C-III, E and lipoprotein (a); oxidative status by alpha-tocopherol, retinol, selenium, glutathione peroxidase, malondialdehyde and advanced oxidized protein products; inflammatory status by serum C-reactive protein, orosomucoid, IL-2 and IL-6. No serious adverse event was observed. Significant changes were observed from day 0 to day 35 (P<0.05): nutritional criteria improved (albumin in OO; albumin, transthyretin and creatinine in SO); LDL-cholesterol, apo B, C-II, C-III and apo A-I/A-II ratio increased in both groups. HDL-cholesterol decreased in OO; apo E increased and lipoprotein (a) decreased in SO; alpha-tocopherol/cholesterol ratio increased in OO; malondialdehyde decreased in both groups; IL-2 increased in both groups. The between-group comparison only showed the following differences: alpha-tocopherol/cholesterol increased in OO; lipoprotein (a) decreased in SO. From these data, it was concluded that OO- and SO-based IDPNs similarly improved nutritional status and influenced plasma lipid, oxidative, inflammatory and immune parameters.

Olive: fruit of peace against cancer.

Abstract
The olive has a history almost as long as that of Western civilization and has been looked upon as a sign of hope, peace, and sacredness. Olive oil, extracted from the olive, is the principal source of dietary fat in the Mediterranean basin. The composition differs from that of other dietary fats in that olive oil is rich in monounsaturated fatty acids. Even other than as a source of monounsaturated fats, olive oil has own unique effects. Accumulating evidence suggests that olive oil may have beneficial health effects, especially when it comes to reducing risk factors for coronary heart diseases, preventing cancer, and modifying immune and inflammatory responses. However, evidence remains limited, definitive conclusions are difficult to draw, and there remains a significant need for further studies, particularly prospective cohort and well-designed, controlled intervention studies. In this manuscript, the beneficial health effects of olive oil are reviewed, with particular attention paid to cancer prevention and immune functions..
