Background: To determine the neuroprotective effect of CSF drainage by analyzing its impact on the expression and the ratio of pro- and anti-inflammatory cytokines in the subventricular zone in kaolininduced hydrocephalic rats. Method: Sprague-Dawley rats of 23 weeks of age (n=36) were used in this study. The rats were randomly divided into normal control, hydrocephalus, and CSF drainage-treated groups. Hydrocephalus was obtained by injecting 0,05 cc of 20\% kaolin suspension into the cisterna magna. The CSF drainage-treated group had ventricular tapping seven days after kaolin induction. The rats were sacrificed 7, 14, or 21 days after kaolin induction. The brain was removed and prepared for immunohistochemistry analysis to detect IL-1β, IL-6, TNF-α, and IL-10 cytokines expression. Results: Immunohistochemistry analysis revealed that the expression of pro-inflammatory cytokines was significantly increased in hydrocephalus groups than in the control group. In contrast, the expression of anti-inflammatory cytokine was significantly decreased. CSF drainage had a neuroprotective effect by reducing pro-inflammatory cytokine expression and increasing anti-inflammatory cytokine expression. In the hydrocephalus group, the ratios of IL-1β/IL-10, IL-6/IL-10, and TNF-α/IL-10 increased toward a pro-inflammatory status. After CSF drainage, the ratios of IL-1β/IL-10, IL-6/IL-10, and TNF-α/IL-10 shifted toward an anti-inflammatory status. Conclusion: CSF drainage protects the brain from excessive neuroinflammatory processes in kaolin-induced hydrocephalic rats. Additional investigation is warranted to ascertain the use of inflammatory cytokines expression as a valuable biomarker for hydrocephalus. Furthermore, research on anti-inflammatory drug administration in clinical settings is required.

Background: Glaucoma is an optic neuropathy caused by the apoptosis of retinal ganglion cells and results in progressive retinal ganglion cell injury. A decrease in intraocular pressure (IOP) is a modifiable risk factor for slowing the progression of the disease, and can be accomplished through medication, laser therapy, or surgery. Even though the intraocular pressure has decreased and attained normal levels, the injury to the retinal ganglion cells continues in some cases. It is believed that neuroprotective administration has a positive effect on preventing the loss of retinal ganglion cells. Methods: Bax and Caspase-3 expression were measured involving 20 eyeballs of Rattus Norvegicus by immunohistochemistry examination. I-R injury was developed by increasing intraocular pressure (IOP) through the intracameral balanced salt solution (BSS) injection, then lowered after 60 minutes. Samples were divided into 4 groups: control, no further injection group, phosphate-buffered saline (PBS)-injected group and resveratrol-injected group. Each group was enucleated at days 7, 0, 7, and 7, respectively. Data with a non-normal distribution were examined using the Kruskal-Wallis test, and if the outcome was significant, the Mann-Whitney test. Results: The highest mean Bax and Caspase-3 expression was found in PBS injected and enucleated at day 7 group (G2), 0.96{\textpm}0.40 and 0.72 {\textpm} 0.30, respectively. When compared to PBS injection, the expression of Bax and Caspase-3 was lower in the resveratrol-injected group. Conclusion: Bax and Caspase-3 expressions were lower in the intravitreal injection of Resveratrol in the dose of 100 {\textmu}M following the I-R injury group compared to the group without intravitreal Resveratrol injection.

Background: Ganoderma lucidum has been used as a medicinal mushroom since centuries in East Asia. Recent reports have shown that metabolites isolated from Ganoderma species have shown effects on central nervous system. Objective:\ To determine the neuroprotective, anticonvulsant, anxiolytic, and sedative effects of Ganoderma sp. and Ganoderma curtisii polysaccharides. Methods: Polysaccharides (Gsp-PS2 or Gc-PS2) were isolated from two Ganoderma mycelia submerged cultures. Acute toxicity effects of Gc-PS2 or Gsp-PS2 on mice were treated orally with doses of 50 - 2000 mg/kg. Anticonvulsant activity was determined using three chemoconvulsants: kainic acid (KA), strychnine, or pentylenetetrazole (PTZ). Anxiolytic-like effects were determined using the elevated plus maze test on mice. GABA release evoked by GC-PS2 or Gsp-PS2 content was determined by HPLC. Neuroprotective effects of Gsp-PS2 or Gc-PS2 were determined by glial activation, histopathological changes, and immunohistochemistry. Results: Gc-PS2 or Gsp-PS2 showed neuroprotective activity by diminishing neuronal death, reducing glial activation and Neu-N expression levels. Gsp-PS2 or Gc-PS2 inhibited convulsions in the KA model. An anxiolytic-like, but not a sedative effect was reported in mice treated with Gc-PS2 or Gsp-PS2. Polysaccharides Gc-PS2 or Gsp-PS2 evoked endogenous GABA release and increased its concentration within the incubation medium. Pretreatment with Gsp-PS2 or Gc-PS2 showed a reduction of the LPSinduced NO production. Gc-PS2 or Gsp-PS2 did not produce toxic effects. Conclusion:\ Ganoderma sp. or Ganoderma curtisii polysaccharides showed neuroprotective and anticonvulsant activities in animal models. The anticonvulsant activity may involve the GABAergic neurotransmision.

Background: Epilepsy is one of the major neurological disorders affecting world population. Although, some Ganoderma species have shown neuroprotective activities, the effects of polysaccharides isolated from Ganoderma curtisii on epileptic seizures have not been reported. Objective: The aims of the present study were to determine whether treatment with a polysaccharide fraction (GCPS-2) from a Mexican Ganoderma curtisii strain can reduce seizures, and the increases in the levels of apoptotic molecules and inflammatory cytokines in kainic acid-induced seizure mouse model. Materials and Methods: Rats were separated in groups: Control group received 2.5\% Tween 20 solution; GCPS-2 groups were administered GCPS-2 (10, 40, or 80 mg/kg); KA group received KA 10 mg/kg; GCPS-2+KA received GCPS- 2 and 30 min later KA. Pathological changes in neuronal morphology, expression of B-cell lymphoma-2, and pro-inflammatory cytokines (interleukin1-β and tumor necrosis factor-α) in the rat hippocampus and cortex were determined by immunohistochemistry. Results: Ganoderma curtisii soluble polysaccharides (GCPS-2) inhibited convulsions in rats. Moreover, treatment with GCPS-2 reduced the increased levels of apoptotic signaling molecules (Bcl-2) and proinflammatory mediators (in the kainic acid-treated hippocampus and cortex). Conclusion: Ganoderma curtisii soluble polysaccharides have a neuroprotective potential against epilepsy, partially through its ability to inhibit neurotoxic events in the in vivo hippocampus and cortex.

Introduction: Effective treatment is necessary to minimize the neuronal damage and oxidative stress. Traditional medicines offer potent pharmacological activity with minimal side effects compared to synthetic drugs to treat such chronic disorders. There is no renowned remedy for arrest or rescuing infection or inflammation-induced brain damage. The present study was aimed to evaluate the neuroprotective effect of ethanol extract of Pedalium murex Linn. (EEPM) leaves against lipopolysaccharide (LPS)-induced endotoxemia. Methods: Neurodegeneration was induced in rats with a single intraperitoneal injection of LPS (1 mg/kg). The induced endotoxemia constantly linked with battery of behavioural tests viz., choice reaction time task (CRT), 8-arm radial maze (RAM) and water maze test (WMT). At the end of the study, rats were sacrificed, brain hippocampal region was removed and biochemical parameters were measured. Results: In WMT swimming length (cm) was increased in LPS-treated rats when compared to control animals, the swimming length (EEPM; 400 mg/kg) was found to be significant; in RAM, different doses of EEPM at 100, 200 and 400 mg/kg decreased the number of errors in entry 4.00\±0.36, 4.16\±0.16and 3.33\±2.79 respectively when compared with control animals (2.66\± 0.21). EEPM at 400 mg/kg showed significant activity, in CRT apparatus increased incorrect lever pressing was observed in LPS-treated rats when compared to control animals. Incorrect lever pressing was minimized by EEPM at 400 mg/kg (43.5\±2.40). Conclusions: Our results showed that EEPM is a hopeful aspirant for hindrance of infection and inflammation induced brain damage by LPS.

Introduction: Herbal medicines are widely used in the therapeutic intervention that could delay the onset of Neurodegenerative diseases like, Alzheimer{\textquoteright}s disease. Despite intensive advancements in the field of research currently available therapeutic strategies are often limited due to their adverse effects. Hence there is a need for the search for novel compounds for effective medications to treat neurocognitive deficits. Objective: The present study focused on acetylcholinesterase inhibitory and neuroprotective activity of Commiphora species plant for their possible use in Alzheimer{\textquoteright}s disease. Methods: Phytochemical screening, TLC bioautographic and colourimetric assay was performed to quantify their acetylcholinesterase inhibitory activity of ethanolic extracts of the Commiphora species. The MTT assay was carried to evaluate the neuroprotective effect against the Aβ-induced cytotoxicity in SHSY5Y cell lines. Results: The bark of Commiphora berryi, leaves of Commiphora caudata and Commiphora pubescens were found abundant in flavonoids, glycosides, steroids and terpenoids. Further, the ethanol extract of Commiphora berryi (65.48\% {\textpm} 0.10) showed the highest acetylcholinesterase inhibitory activity. The Aβ25-35 induced cell damage was as evidenced at a concentration of 20μM. The neuroprotective effect of the ethanol extracts was examined in neurodegenerative cells induced by Aβ25-35. On pretreatment with plant extracts, significant improvement in cell viability was observed as 63.42 {\textpm} 2.02\% (25μg/ml) for Commiphora berryi. The maximum percentage of in-vitro AChE inhibition and neuroprotective effect was effective in the ethanol bark extract of Commiphora berryi. Conclusion: The results are very rousing to continue the screening of more unexplored plant species could be used for the development of novel bioactive compounds to treat the many diseases, especially for Alzheimer{\textquoteright}s disease.
