Abstract
Colostrum, which contains various immune and growth factors, aids wound healing by promoting keratinocyte proliferation. Aquaporins (AQPs) are small, hydrophobic membrane proteins that regulate cellular water retention. However, few studies have examined the effect of processed colostrum whey on AQP-3 expression in human skin cells. Here, we investigated the effect of milk, colostrum, fermented milk, and fermented colostrum whey on AQP-3 expression in keratinocyte HaCaT cells. Concentrations of 100-400 μg/mL of fermented colostrum whey were found to induce HaCaT cell proliferation. AQP-3 was found to be expressed exclusively in HaCaT cells. AQP-3 expression was significantly increased in 100 μg/mL fermented colostrum whey-treated cells compared with that in controls. Moreover, fermented colostrum increased p38 mitogen-activated protein kinase (MAPK) and c-Jun N-terminal kinase (JNK) phosphorylation, but not ERK1/2 phosphorylation. Thus, our results suggest that fermented colostrum whey increased AQP-3 expression in, and the proliferation of, keratinocytes via JNK and p38 MAPK activation.

Abstract
In its early life a kitten faces many significant events including separation from its mother, re-homing and vaccination. The kitten is also slowly adapting to their post-weaning diet. Recent advances in companion animal nutrition have indicated that functional ingredients such as colostrum can help support the immune system and gastrointestinal health. Here we report for the first time the effect of feeding a diet containing 0.1% spray dried bovine colostrum (BC) to growing kittens on gut-associated lymphoid (GALT) tissue responses, systemic immune responses, and on intestinal microbiota stability. BC supplementation induced increased faecal IgA expression, and a faster and stronger antibody response to a rabies vaccine booster, indicative of better localised and systemic immune function, respectively. BC supplementation also helped to maintain kittens' intestinal microbiota stability in the face of a mildly challenging life event. These results show that BC supplementation can help strengthen the immune system and enhance the gut microbiota stability of growing kittens.

Abstract
Administration of oropharyngeal colostrum (OPC) is safe, feasible, and potentially beneficial in preterm infants. We aimed to assess the effects of OPC in preterm infants. A systematic review of randomized controlled trials (RCTs) and non-RCTs of OPC administration in preterm infants was conducted. We searched MEDLINE via PubMed and Ovid, EMBASE, the Cochrane Central Register of Controlled Trials, Emcare databases, abstracts of Pediatric Academic Societies meetings, and gray literature in April 2018. Six RCTs (n = 269) and 4 non-RCTs (n = 737) were included. One RCT (n = 40) focused on enteral bovine colostrum and hence was excluded from our review. Five of the 6 RCTs had unclear risk of bias in many domains of assessment. Meta-analysis (random effects model) of RCT data showed no significant difference in ≥stage 2 necrotizing enterocolitis (RR: 0.83; 95% CI: 0.39, 1.75; P = 0.62), late-onset sepsis (RR: 0.78; 95% CI: 0.50, 1.22; P = 0.28), all-cause mortality (RR: 0.74; 95% CI: 0.27, 2.06; P = 0.56); duration of hospital stay (mean difference [MD]: -1.65 d; 95% CI: -10.09, 6.80; P = 0.70), and time to full feeds (MD: -2.86 d; 95% CI: -6.49, 0.77; P = 0.12). Meta-analysis of data from non-RCTs also showed no benefit for any of these outcomes. OPC increased secretory IgA and lactoferrin concentrations (4 RCTs), and had only a transient effect on the oral microbiome (1 RCT). There were no adverse effects (e.g., aspiration) of OPC. The overall quality of evidence (Grades of Recommendation, Assessment, Development, and Evaluation analysis) was very low. Adequately powered RCTs are needed to confirm the nutritional and immunomodulatory benefits of OPC in preterm infants.

Effect of dietary bovine colostrum on the responses of immune cells to stimulation with bacterial lipopolysaccharide. Arch Pharm Res 2015; 37:494-500.

Abstract
Previous studies have revealed that ingestion of bovine colostrum is effective in preventing pathogens from invading through the gastrointestinal tract (GI) and modulating the mucosal immunity of the GI tract, indicating that its effect is principally local. Thus it is unclear if ingestion of bovine colostrum can affect the systemic immune system. In this study, we investigated the effect of taking bovine colostrum (vs phosphate-buffered saline) for 14 days on the behavior of the immune cells of mice. Isolated splenocytes, which are pivotal cells of systemic immunity, were then stimulated with Escherichia coli lipopolysaccharide. Bovine colostrum significantly reduced NK cell and monocyte activities and lymphoproliferaltive responses to LPS stimulation. Thus dietary bovine colostrum renders immune cells less responsive to LPS stimulation. Dietary bovine colostrum thus affects the systemic immune system and may have anti-inflammatory actions.

Abstract
BACKGROUND AND AIM Increasing evidence has indicated a close association of host-gut flora metabolic interaction with obesity. Flos Lonicera, a traditional herbal medicine, is used widely in eastern Asia for the treatment of various disorders. The aim of this study was to evaluate whether unfermented or fermented formulations of Flos Lonicera could exert a beneficial impact to combat obesity and related metabolic endotoxemia. METHODS Obesity and metabolic endotoxemia were induced separately or together in rats through feeding a eight-week high fat diet either alone (HFD control group) or in combination with a single LPS stimulation (intraperitoneal injection, 0.75 mg/kg) (LPS control group). While, the mechanism of action of the Lonicera formulations was explored in vitro using RAW 264.7 and HCT 116 cell lines as models. RESULTS In cell-based studies, treatment with both unfermented Flos Lonicera (UFL) and fermented Flos Lonicera (FFL) formulations resulted in suppression of LPS-induced NO production and gene expression of vital proinflammatory cytokines (TNF-α, COX-2, and IL-6) in RAW 264.7 cells, reduced the gene expression of zonula occludens (ZO)-1 and claudin-1, and normalized trans epithelial electric resistance (TEER) and horseradish peroxidase (HRP) flux in LPS-treated HCT-116 cells. In an animal study, treatment of HFD as well as HFD+LPS groups with UFL or FFL resulted in a notable decrease in body and adipose tissue weights, ameliorated total cholesterol, HDL, triglyceride, aspartate transaminase and endotoxin levels in serum, reduced the urinary lactulose/mannitol ratio, and markedly alleviated lipid accumulation in liver. In addition, exposure of HFD as well as HFD+LPS groups with UFL or FFL resulted in significant alteration of the distribution of intestinal flora, especially affecting the population of Akkermansia spp. and ratio of Bacteroidetes and Firmicutes. CONCLUSION This evidence collectively demonstrates that Flos Lonicera ameliorates obesity and related metabolic endotoxemia via regulating distribution of gut flora and gut permeability.

Abstract
Brain cell death after intracerebral hemorrhage may be mediated in part by an apoptotic mechanism. Colostrum is the first milk produced by mammals for their young. It plays an important role in protection and development by providing various antibodies, growth factors and nutrients, and has been used for various diseases in many countries. In the present study, we investigated the anti-apoptotic effects of bovine colostrum using organotypic hippocampal slice cultures and an intracerebral hemorrhage animal model. We performed densitometric measurements of propidium iodide uptake, a step-down avoidance task, Nissl staining, and caspase-3 immunohistochemistry. The present results revealed that colostrum treatment significantly suppressed N-methyl-D-aspartic acid-induced neuronal cell death in the rat hippocampus. Moreover, colostrum treatment improved short-term memory by suppressing hemorrhage-induced apoptotic neuronal cell death and decreasing the volume of the lesion induced by intracerebral hemorrhage in the rat hippocampus. These results suggest that colostrum may have a beneficial role in recovering brain function following hemorrhagic stroke by suppressing apoptotic cell death.

Abstract
Oral administration of immunoglobulin in the colostrum or egg yolk has been considered an effective tool for preventing enterobacterial infection via passive immunization. During this process, the transmission and residence of the active immunoglobulin are the most important conditions for successful protection. We investigated the stability of encapsulated colostrum and egg yolk immunoglobulin for the effective transmission of immunoglobulin in the gastrointestinal (GI) tract. First, we measured GI transit time. Contrast media passed through and reached the stomach within 10 min, the small intestine within 3.5 h, and the cecum within 5 h. Both the encapsulated colostrum containing anti-hepatitis A virus (HAV) antibody (IgG) and egg yolk with anti-rotavirus antibody (IgY) showed lower antibody activity than the non-encapsulated colostrum did in the stomach after administration; however, significantly higher antibody activities were observed in the encapsulated groups than in the non-encapsulated groups in the small intestine 3.5 h after the administration. In the large intestine, the antibody activities of the encapsulated groups were maintained or slightly increased in a time-dependent manner; however, the titers of each non-capsulated control were as low as the negative controls. Therefore, this encapsulation is considered a useful tool for the delivery of active antibody through the GI tract.

Abstract
INTRODUCTION Immunoglobulin A (IgA)-deficient patients predominantly suffer from respiratory and gastrointestinal infections since secretory IgA has important functions to protect mucosal surfaces. OBJECTIVE To evaluate the effect of bovine colostrum, rich in IgA, on the treatment of viral upper respiratory tract (URT) infections in IgA-deficient children. METHODS Thirty-one IgA-deficient children with viral URT infections were included in this double-blind, placebo-controlled study, and randomly oral bovine colostrum or placebo was given three times a day for 1 week. Samples of saliva IgA were collected before treatment, after the administration of the first dose, and after the last dose. Mothers of the children completed a daily questionnaire regarding the severity of the infection and any adverse effects. RESULTS The bovine colostrum group had a lower infection severity score than the placebo group after 1 week (respectively 0.81±0.83, 3.00±1.85; P=0.000), but there was no difference between the salivary IgA levels of the groups. CONCLUSION This is the first study to evaluate the effect of bovine colostrum in IgA-deficient children, and no adverse effects were observed. However, further studies are needed to confirm the efficacy and safety of bovine colostrum in IgA-deficient patients.

Abstract
Immunoglobulin-containing food products and nutraceuticals such as bovine colostrum are of interest to consumers as they may provide health benefits. Commercial scale colostrum products are valued for their immunoglobulin G (IgG) content and therefore require accurate analysis. One of the most commonly used methods for determining total soluble IgG in colostrum products is based on affinity chromatography using a Protein G column and UV detection. This paper documents improvements to the accuracy of the Protein G analysis of IgG in colostrum products, especially those containing aggregated forms of IgG. Capillary electrophoresis-sodium dodecyl sulfate (CE-SDS) analysis confirmed that aggregated IgG measured by Protein G does not contain significant amounts of casein or other milk proteins. Size exclusion chromatography identified the content of soluble IgG as mainly monomeric IgG and aggregated material MW > 450 kDa with small amounts of dimer and trimer. The turbidity of the eluting IgG, mainly associated with aggregated IgG, had a significant effect on the quantitative results. Practical techniques were developed to correct affinity LC data for turbidity on an accurate, consistent, and efficient basis. The method was validated in two laboratories using a variety of colostrum powders. Precision for IgG was 2-3% (RSD(r)) and 3-12% (RSD(R)). Recovery was 100.2 ± 2.4% (mean ± RSD, n = 10). Greater amounts of aggregated IgG were solubilized by a higher solution:sample ratio and extended times of mixing or sonication, especially for freeze-dried material. It is concluded that the method without acid precipitation and with turbidity correction provides accurate, precise, and robust data for total soluble IgG and is suitable for product specification and quality control of colostrum products.

Abstract
OBJECTIVE The objective of the study was to evaluate the clinical efficacy of oral bovine colostrum in the management of nonorganic failure to thrive (FTT). MATERIALS AND METHODS In a randomized clinical trial, 120 children (1-10 years of age) of either sex with mild or moderate nonorganic FTT were divided into 2 groups. Both groups were matched with regard to age, sex, weight, and height. One group (control) received routine treatments for FTT and the other group (case), besides routine treatments, received supplementary bovine colostrum at the dose of 40 mg . kg . day for a 3-month period. Following the initial visit, subsequent visits were completed following 1, 2, and 3 months of supplementation. For quantitative measurements, Waterlow I (height for age) and Gomez (weight for age) indices were used. RESULTS The mean value of Gomez index in the case group (81.72) was significantly higher than the control group (77.12) at the end of the third month of supplementation (P = 0.003). Such a difference was not reported based on Waterlow I index between the case and control groups (92.91 vs 91.71; P = 0.094). According to Gomez index 12 patients (20%) who received colostrum became healthy at the end of the third month, which was significantly higher than the control group (2 cases, 3.3%); P = 0.006. CONCLUSIONS Bovine colostrum supplementation for a 3-month period is a useful method without any side effects, in addition to known medical and psychological treatments, to increase the weight of children with nonorganic FTT.

Abstract
Helicobacter pylori (H. pylori) live in the stomach of human. It is a kind of curve bacteria which can lead to chronic gastritis, peptic ulcer and gastric cancer. Usually, antibiotics are used to treat the patients, but they have a lot of side effects. Milk of milch cow immunized with H. pylori vaccine can prevent and treat the infection of H. pylori without side effects. During the production of immune milk, the basic work is to prepare vaccine. During the preparation of sub-unit vaccine, key is to isolate and purify the antigen protein. In this article, we discuss the culture of H. pylori (solid and liquid culture), the recombinant expression and purification of its antigen protein (urease, VacA, CagA and lipopolysaccharide).
